Question

present ages of a and b are jn ratio 2:3.Four years from now the ratio will be 6:7 find their present ages​

Answer 1

Step-by-step explanation:

A : B = 2 : 3

Let their ages be 2a and 3a.

So, A = 2a

B = 3a

After 4 years, their ages A = 2a + 4

B = 3a + 4

A.T.Q., A = 6

B = 7

So, 2a + 4 / 3a + 4 = 6 / 7

7 ( 2a + 4 ) = 6 ( 3a + 4 )

14a + 28 = 18a + 24

28 - 24 = 18a - 14a

4 = 4a

4 / 4 = a

1 = a

age of A = 2a = 2 × 1 = 2 years

age of B = 3a = 3 × 1 = 3 years
