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

9. 5

Cost of per sqm carpet = 301920/(85*74) = 48

10. 2

Avg = 347874/6 = 57979
