**Study the following information and answer the given questions:**

There are certain number of candidates studying in a college. In a survey it is found that 45.6% of total number of candidates like tea. 12.8% of total number of candidates like cold drink. 84.4% of total number of candidates like milk. 7% of candidates do not like any drink. 3.6% candidates like tea and cold drink. 10.2% of total candidates like cold drink and milk. 38.6% of total candidates like tea and milk. 2.6% candidates like all three drinks. Number of candidates who do not like any drinks is 35.

- What is the number of candidates who like only milk?
191180188205None of theseOption A

Number of candidates who don’t like any drink=35

Therefore,7%=35 henece,100%=500(total candidates) - What is the number of candidates who like tea and cold drink but don’t like milk?
8515911Option B
- What is the number of candidates who like exactly two drinks out of the given three options?
225235229223None of theseOption D
- What is the number of candidates who like at least one drink?
450455395465None of theseOption D
- What is the number of candidates who like at least two drinks?
236205215284None of theseOption A
- The person finds that his son’s age after ‘x’ years will be 3/8th of his age at that time, his wife finds that ratio of age of his only son after x years to her age at that time will be 3:7. Find the average of their (all three) present age?

a) That person is 5 years older than that of his wife.

b) Ratio of present age of father to that of his son is 6:1.Statement a alone is sufficient to answer the question, but statement b alone is not sufficient to answer the questionsStatement b alone is sufficient to answer the question, but statement a alone is not sufficient to answer the question.Both the statements taken together are necessary to answer the questions, but neither of the statements alone is sufficient to answer the question.Either statement a or statement b by itself is sufficient to answer the question.Statements a and b taken together are not sufficient to answer the question.Option C

Let person age after x years be 8p years

Then his son’s after x years 3p years

Wife’s age after x years=3p/3 *7=7p yeARS

From statement A,

8p-7p=5

p=5

FRom statement B,

8p-x/3p-x = 6/1

x=10

Therefeore,sum of present ages of all three=60 years

Req avg=20 years - Ratio of distance covered by boat in upstream to that in downstream is 2:3 and time taken by boat to cover that upstream distance is equal to the time taken by the boat to cover those downward distance. Find the speed of boat in still water?

a) Difference of speed of boat in still water to that of speed of boat in upstream is 5 km/hr.

b). Boat will cover 50 km of distance in upstream in 2.5 hours.Statement a alone is sufficient to answer the question, but statement b alone is not sufficient to answer the questions.Statements a and b taken together are not sufficient to answer the question.Either statement a or statement b by itself is sufficient to answer the question.Both the statements taken together are necessary to answer the questions, but neither of the statements alone is sufficient to answer the question.Statement b alone is sufficient to answer the question, but statement a alone is not sufficient to answer the question.Option C - We have to choose from 6 female and 9 male for the post of HRMS and Management in-charge in which minimum 2 female has to be selected. What is the probability that both the persons selected are un-married?

a)only 2 female are married.

b)The number of male who were unmarried was twice of number of unmarried female.Both the statements taken together are necessary to answer the questions, but neither of the statements alone is sufficient to answer the question.Statement b alone is sufficient to answer the question, but statement a alone is not sufficient to answer the question.Either statement a or statement b by itself is sufficient to answer the question.Statement a alone is sufficient to answer the question, but statement b alone is not sufficient to answer the questions.Statements a and b taken together are not sufficient to answer the question.Option A

To calculate required probbility,we must know both the number of married ,unmarried male and female.

Therefore,both sttements are required. - Three persons Akansha, Banya and Caryl together can do a work in 8 days while Akansha, Banya and Dinesh together can do that work in 15/2 days. Find in how many days Banya alone will do that work?

a). Akansha alone takes 4 days less than that of Caryl alone to do that work and time taken by Akansha alone and Dinesh alone to do that work is equal.

b) Ratio of efficiency of Akansha to that of Banya is 3:2 and ratio of efficiency of Caryl to that of Dinesh is 5:6.Statements a and b taken together are not sufficient to answer the question.Statement a alone is sufficient to answer the question, but statement b alone is not sufficient to answer the questions.Either statement a or statement b by itself is sufficient to answer the question.Option E - At the end of a year of starting a business, Priyanka and Queen earns total profit of Rs. 60,000, calculate the profit-share of Queen?

a)Queen invested Rs. 40000 more than Priyanka.

b)Both of them invested for 12 months, but Priyanka also take 20% of total profit as a salary share.Statements a and b taken together are not sufficient to answer the question.Either statement a or statement b by itself is sufficient to answer the question.Option C

Total profit=Rs 60000

From A,

Let Priyank invesed Rs x,

Then Queen invested (x+30000)

And futher nothing can be obtained.

From B,

Priyanka got as salay=20/100 *60000=12000

But again,cant be futher solved.
