Answer 1

Given:

a = 3b

c = 2a

= 2(3b)

= 6b

After 4 years 'a' is 31 years old

thus age of c = 2a

= 2(31)

= 62

age of b is ,

c = 6b

62 = 6b

62/6 = b

10.33..... = b

here, 10 years = b .....(approximately)

thus present age = age - 4 years

thus ....

a = 31-4

a = 27.......(I)

.

b = 10-4

b = 6 ......(II)

.

c = 62-4

c = 58.......(III)

thus answer proved .....

and justified....
