Directions(1-5): What value should come in place of question mark ‘?’ in the following questions?

1. 1(1/4) + 1(5/9) * 1(5/9) / 6(1/2) = ?
1(23/46)
5(22/59)
3(27/41)
1(23/36)
1(21/37)
Option D
1(1/4) + 1(5/9) * 1(5/9) / 6(1/2) = ?
=> ? = 5/4 + 14/9 *13/8 *2/13
=> ? = 1(23/36)

2. (5^2 *14 – 6*7 + 4^? )^1/2= 18
4
6
2
8
10
Option C
(5^2 *14 – 6*7 + 4^? )^1/2= 18
=> 324 = 25*14 – 42 + 4^?
=> 4^? = 324 – 308 = 16
=> ? = 2

3. 7/11 of 6908 – 4/9 of 7704 = ? * 72
13.5
11.7
18.2
23.3
8.2
Option A
7/11 of 6908 – 4/9 of 7704 = ? * 72
=> 4396 – 3424 = 72 * ?
=> ? = 13.5

4. 65% of 768 + 35% of 864 = ?
705.5
691.9
603.5
700.3
801.6
Option E
65% of 768 + 35% of 864 = ?
499.2 + 302.4 = 801.6

5. 4571 * 72 * = ? * 18 + 3621 * 36
11042
11000
12002
13046
15050
Option A
4571 * 72 * = ? * 18 + 3621 * 36
=> 18x = 36(4571*2 – 3621)
=> x = 11042

6. Two trains start from stations A and B travel towards each other at speed of 50 km/hr. and 60 km/hr. resp. At the time of their meeting the second train has travelled 120 km more than the first. Find the distance between A and B.
1000 km
1320 km
1150 km
1220 km
1450 km
Option B
Let the trains meet after t time.
Then, 60t – 50t = 120
=> t = 12 hr.
Distance from A to B = 50*12 + 60*12 = 1320 km

7. A playground is in the shape of a rectangle. A sum of Rs. 1000 was spent to make the ground usable at the rate of 25 paise per metre square. The breadth of the ground is 50m. If the length of the ground is increased by 20 m, what will be the expenditure (in Rupees) at the same rate per metre square.?
Rs.1010
Rs.1720
Rs.1250
Rs.1440
Rs.1200
Option C
Area of a rectangular field = 1000/0.25
= 4000 m sq.
Length = 4000/50 = 80 m
New length = 80 + 20 = 100 m
New area = 100 * 50 = 5000 m sq.
New expenditure = 5000*(25/100) = Rs.1250

8. A 10 hectare of a field is reaped by 2 men, 3 women and 4 children together in 10 days. If working capabilities of a man, a woman and a children are in the ratio 5:4:2, then in how many days a 16 hectare field will be reaped by 6 men, 4 women and 7 children?
6 days
4 days
8 days
12 days
10 days
Option C
One day work of 2 men = 10 units One day work of 3 women = 12 units
One day work of 4 children = 8 units Let time taken be T.
(10+12+8)*10/10 = [(6*5) + (4*4) + (7*2)]*T /16
=> 30 * 16 = T * 60
=> T = 8 days

9. Rajesh has a total of Rs.42,000. And in that, he lends Rs.8,000 at 9/2% per annum simple interest and Rs.12,000 at 8% per annum simple interest. He lends the remaining money at a certain rate of interest so that he gets total interest of Rs. 3600 at the end of one year. The rate of interest per annum, at which the remaining money is lent, is?
31.03%
20.26%
15.15%
10.36%
11.33%
Option D
For first loan 𝑆𝐼 = 𝑃*𝑁*𝑅/ 100
= 8000×9×1/ 100×2 = 360
For Second loan=12000×8×1/100 = 960
Total interest = 3600 So for the third loan
SI = 3600 – (960+360) = 2280
Rate of interest for third loan = 2280×100/22000 = 10.36%

10. I forgot the last digit of a 7-digit telephone number. If 1 randomly dial the final 3 digits after correctly dialling the first four, then what is the chance of dialling the correct number?
1/5000
1/3000
1/2000
1/1000
1/4000
Option D
It is given that last three digits are randomly dialled. Then each of the digit can be selected out of 10 digits in 10 ways.
Hence, required probability =(1/10)^3 = 1/1000
