Answers:
1. 2
Let the present age of these two persons are ‘x’ & ‘y’
(x + y)/2 = 46
x + y = 92
(x - 16)/(y - 16) = 1/2
2x - 32 = y - 16
2x - y = 16

Hence, x = 36 years & y = 56 years
Difference = 56 - 36 = 20

2. 4

Total number of letters is six and their is no repeatation.

So number of arrangements = 6! = 720

3. 2
Population = 480000 * 108/100 * 91/100 = 471744

4. 3
Let the total distance is 'x' km
x/(2 * 30) + x/(2 * 40) = 24.5
x/6 + x/8 = 245
(4x + 3x)/24 = 245
x = (245 * 24)/7 = 840 km

5. 4
Area of wall = 24 × 16 = 384 sqm
Area from both side = 2 × 384 = 768 sqm
Cost of painting = 768 × 8 = 6144

6. 2
Let the pruchase rate be ‘x’
Then, printed price = x + x * 20/100 = 6x/5
After 15% discounts, the price = 6x/5 - 6x/5 * 15/100 = 51x/50
51x/50 = 867
x = (867 * 50)/51 = 850

7. 5
Let his salary be x
x * 75/100 * 80/100 * 92/100 = 6624
x = 12000
Amount on clothes = 12000 * 80/100 * 75/100 * 8/100 = Rs. 576

8. 4
Let the water added be ‘x’ litre. Initially water was
15% of 60 litre ie 60 × 15/100 = 9 litres now water is (9 + x) litre
9 + x = (60 + x) × 100
40
45 + 5x = 120 + 2x
3x = 120 – 45 = 75
x = 25 litres

9. 1

(A + B)'s 1 day work = 1/40 + 1/60 = (3 + 2)/120 = 1/24
which is equal to C's 1 day work
(A + B + C)'s 1 day work
= 1/40 + 1/60 + 1/24 = (3 + 2 + 5)/120 = 1/12
(A + B + C) can finish the work in 12 days.

1. 4

Let the breath of flat is x

Length = 7x/3

x * 7x/3 = 18900

x^2 = 8100

x = 90

Length = 7 * 90/3 = 210

Perimeter = 2(210 + 90) = 600m

2. 2

Let the number be 'x'.

18/100 * x * 11/17 = 306.9

x = (306.9 * 100 * 17)/(11 * 18) = 2635

28% of 2635 = 28/100 * 2635 = 737.8

3. 1

A’s profit : B’s profit = 15000 × 12 : 20000 × 6 = 3 : 2

B’s profit = 5785/5 * 2 = Rs. 2314

4. 3

Let number of boy is ‘5x’ and number of girls is ‘2x’

5x – 2x = 648

x = 648 ÷ 3 = 216

Boys = 5x = 216 × 5 = 1080,

Girls = 2x = 2 × 216 = 432

Total = 1080 + 432 = 1512

5. 2

Let the present age of Sohan and Vikky are ‘x’ & ‘y’

x/y = 3/2

2x = 3y

(x - 8)/(y - 8) = 7/4

4x - 32 = 7y - 56

4x = 7y - 24

x = 36 & y = 24

Difference = 36 - 24 = 12

6. 3

Cost price of 3 radios = 1850 × 3 = 5550, after repair

total cost is 5550 + 750 = 6300

Now profit is 24%

SP = 6300 * (100 + 24)/100 = 7812

SP per ratio = 7812/3 = 2604

7. 1

r = {(2295 - 1700) * 100}/1700*7 = 5%

New rate = 5 + 7 = 12%

SI = 1700*12*7/100 = 1428

Total amount = 1700 + 1428 = 3128

8. 2

Let the salary of A is ‘x’

B’s salary = x + x * 15/100 = 115x/100 = 23x/20

C's salary = x + x * 35/100 = 135x/100 = 27x/20

7x/2 = 27300

x = 7800 = A's salary

B's salary = 23x/20 = 23/20 * 7800 = 8970

C's salary = 27x/20 = 27/20 * 7800 = 10530

Difference = 10530 - 8970 = 1560
