Directions: The following questions are accompanied by three statements I, II and III. You have to determine which statement/s is/are sufficient to answer the question.
- What is the amount invested by A?
Statement I: Total amount received by B after 3 years is Rs.4800 at compound interest.
Statement II: B and A invested their amount at the rate of 10% per annum.
Statement III: A and B invested their amount at simple interest and compound interest respectively and the difference between the interests received by both after 2 years is Rs.1200.
Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption E
From statement I,
Let the amount invests by B = x
4800 = x * (1 + R/100)^3
So, Statement I alone is not sufficient to answer the question.
From statement II,
R = 10%
So, Statement II alone is not sufficient to answer the question.
From statement III,
Let the amount invests by A = x
Let amount invests by Bl = y
SI = y * 2 * R/100 = yR/50
CI = x * (1 + R/100)2 – x
CI – SI = 1200
or
SI – CI = 1200
So, Statement III alone is not sufficient to answer the question. - What is the sum of the ages of person 1 and 2?
Statement I: Ratio of the ages of 1 to 3 is 4: 5 and the ratio of the ages of 1 to 4 is 1: 3.
Statement II: Sum of the ages of 2,3 and 4 is 125 years and 5 years ago the ratio of the ages of 1 to 4 is 3: 11.
Statement III: 4’s age is 200% more than that of 1’s age and the difference between the ages of 1 and 4 is 40 years.
Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption A
From statement I,
p1/p3 = 4/5
p1/p4 = 1/3
So, Statement I alone is not sufficient to answer the question
From Statement II,
p2 + p3 + p4 = 125
(p1 – 5)/(p4 – 5) = 3/11
So, Statement II alone is not sufficient to answer the question
From statement III,
p4 = 300/100 * p1
p4: p1 = 3: 1
2x = 40
x = 20
p1= 20 years
p4 = 3 * 20 = 60 years
So, Statement III alone is not sufficient to answer the question
From statement I and II,
p1 and p4’s present age be x and 3x respectively
(p1 – 5)/(p4 – 5) = 3/11
(x – 5)/(3x – 5) = 3/11
= > 11x – 55 = 9x – 15
= > 2x = 40
= > x = 20
Present age of p1 and p4 is 20 and 60 years respectively
p3’s present age = 20/4 * 5 = 25 years
p2’s present age = 125 – (25 + 60) = 125 – 85 = 40 years
Sum of the ages of p1 and p2 = (20 + 40) = 60 years
Hence, statement I and II alone is sufficient to answer the given question. - What is the total surface area of the conical box?
Statement I: Ratio of height of the box to height of the cylindricall box is 2: 1.
Statement II: Height of the cylindrical box is equal to the perimeter of the square whose area is 9 cm2.
Statement III: Radius of the cone is equal to length of the rectangle whose perimeter is 20 cm.
Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption E
Height of cone/height of the cylinder = 2/1
So, Statement II alone is not sufficient to answer the question
From statement II,
Area of the square = 9
Side of the square = 3
Perimeter of the square = 3 * 4 = 12 cm
Height of the cylinder = 12 cm
So, Statement II alone is not sufficient to answer the question
From statement III,
Radius of the cone = length of the rectangle
Perimeter of the rectangle = 2 * (l + b) = 20
So, Statement III alone is not sufficient to answer the question - There are four members p1, p2, p3 and p4 partners in the business. What is the profit share of p2?
Statement I: p1 and p2 started the business with investment of Rs.x and Rs.2x respectively and after 6 months p3 and p4 joined them with investment of Rs.(x + 1000) and Rs.3x respectively.
Statement II: At the end of one years and profit Share of p3 is Rs.4000.
Statement III: At the end of one year the profit ratio of p3 and p4 is 2:3.
Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption D
From statement I,
p1= x
p2 = 2x
p3= (x + 1000)
p4 = 3x
So, Statement I alone is not sufficient to answer the question
From Statement II,
p3’s share = Rs.4000
So, Statement I alone is not sufficient to answer the question
From statement III,
Profit ratio of p3/p4 = 2/3
So, Statement III alone is not sufficient to answer the question
From I, II and III
Profit ratio of p1, p2, p3 and p4 = x * 12: 2x * 12: (x + 1000) * 6: 3x * 6
=12x: 24x: (6x + 6000): 18x
(6x + 6000)/18x = 2/3
6x + 6000 = 12x
x = 1000
Profit ratio = 12000: 24000: 12000: 18000
= 2: 4: 2: 3
p2’s profit share = 4/2 * 4000 = 8000
All the statements are necessary to answer the question. - What is the initial quantity of the juice in vessel A?
Statement I: Ratio of the juice and water in vessel A and B is 3: 2 and 4: 3 respectively.
Statement II: 28 liters of the mixture of B is poured into A and then the ratio of the juice and water in vessel A becomes 17: 12.
Statement III: 10 liters of the mixture from vessel C is taken out and is poured into vessel A, then the ratio of the juice to water becomes vessel A is 5: 4.Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption A
From statement I,
juice and water in A = 3: 2
juice and water in B = 4: 3
So, Statement I alone is not sufficient to answer the question
From statement II,
Vessel B mixture = 28
Ratio of the juice and water in A = 17: 12
So, Statement II alone is not sufficient to answer the question
From statement III,
Mixture of C = 10
Ratio of juice and water in C = 5: 4
So, Statement III alone is not sufficient to answer the question
From I and II
juice in 28 liters of B = 4/7 * 28 = 16 liters
Water in 28 liters of B = 3/7 * 28 = 12 liters
3x + 16/2x + 12 = 17/12
34x + 204 = 36x + 192
2x = 12
x = 6
juice in vessel A = 3 * 6 = 18 liters
So, Statement I and II are necessary to answer the question. - What is the difference between the total number of employees from A in all the three years together and the number of males from Company A in three years together?
Statement I: The ratio of the number of males to females from Company A in 2015 is 3:2 and the number of females from company A in 2014 is 20 more than that of the number of males from A in 2016.
Statement II: If the total number of employees from company A in 2014, 2015 and 2016 60%, 40% and 50% respectively are females.
Only IOnly IIEither I or II sufficientAll I and II necessary to the answer the questionThe question can’t be answered even with all I and IIOption B
From statement I,
Females from A in 2015 = 2/5 * 250 =100
Males from A in 2015 = 3/5 * 250 =150
So, Statement I alone is not sufficient to answer the question.
From statement II,
Females from A in 2014 = 60/100 * 400 = 240
Males from A in 2014 = 400 – 240 = 160
Females from A in 2015 = 40/100 * 250 = 100
Males from A in 2015 = 250 – 100 = 150
Females from A in 2016 = 50/100 * 300 = 150
Males from A in 2016 = 300 – 150 = 150
Total number of employees from A = 400 + 250 + 300 = 950
Males from A = 150 + 150 + 160 = 460
Difference = 950 – 460 = 490
So, Statement II alone is sufficient to answer the answer. - What is the ratio of the males to females from company C in 2014?
Which of the following statement is sufficient to answer the question?
Ratio of the males to females from company A and B in 2014 is 1: 3 and 2: 1 respectively and total employees in 2014 from all the companies together 60% are females.The number of females from C in 2014 is half of the number of males from B in 2015.Ratio of the number of males to females from C in all the years together is 3: 2 and the 50% of the employees from C in 2015 is females.40% of the employees from C in 2014 is left and in this 80% of the employees is girlCannot be determineOption A
From option (A)
Females from A in 2014 = 400 * ¾ =300
Females from B in 2014 = 1/3 * 300 =100

From option (D)
Number of employees left from C in 2014 = 200 * 40/100 = 80
Number of females left from C in 2014 = 80 * 80/100 = 64
This not satisfied the given condition. - Number of females from B in all the years together is what percent of the total number of employees from B in all the years together?
Statement I: Total number of employees from B in 2017 is 280 and the ratio of the number of females to males from B in 2017 is 4: 3.
Statement II: 60% of the total number of employees from B in 2014 to 2017 is males.
Only IOnly IIEither I or II sufficientAll I and II necessary to the answer the questionThe question can’t be answered even with all I and IIOption D
From statement I,
Number of females from B in 2017 = 4/7 * 280=160
Number of males from B in 2017 = 3/7 * 280=120
So, statement I alone is not sufficient to answer the question.
From statement II,
60% of the total number of employees from B in 2014 to 2017 is males.
So, statement II alone is not sufficient to answer the question.
From I and II,
Total number of employees from B in 2014 to 2017 = 300 + 100 + 350 + 280 = 1030
Number of males from B in 2014 to 2017 = 1030 * 60/100 = 618
Number of males from B in 2014 to 2016 = 618 – 120 = 498
Number of females from B in 2014 to 2016 = (300 + 100 + 350) – 498 = 252
Required percentage = 252/750 * 100 = 33.6%
Both the statements are necessary to answer the question. - Ratio of the males to females from A, B and C in 2016 is 7: 8, 4: 3 and 2: 3 respectively and the ratio of total number of males from A, B and C in 2017 to the number of males from A, B and C in 2016 is 1: 2.
