Question

Sushil was thrice as old as snehal 6 years back .Sushil will be five thirds times as old as snehal 6 years hence how old is sushil today

Answer 1

Sushil's age = a

Snehal's age = b

6years back

Snehal's age = b - 6

Sushil's age = a -6 = 3(b - 6)

a - 6  = 3b - 18

3b - a = 12  ...........(1)

after 6years

Snehal's age = b + 6

Sushil's age  = a +6 = 5/3(b+ 6)

3a + 18 = 5b + 30

3a - 5b = 12   ..................(2)

3 x (1)

9b - 3a = 36  .............(3)

(2) + (3)

3a - 5b + 9b - 3b = 12 + 36

4b = 48

b = 12

3b - a = 12

36 - a  = 12

a = 24

Snehal's age = 12

Sushil's age = 24
