Answer 1

et the age of Seema be 4x and Shruti be 5x

Eight years from now, Seema's age will be 5x and Shruti's age will be 6x


A/q,


4x + 8 + 5x + 8 = 5x + 6x

9x + 16 = 11x

16 = 11x - 9x

2x = 16

x = \dfrac{16}{2}216​ 

x = 8 years



Present age of Seema => 4x => 4 × 8 => 32 years

Present age of Shruti => 5x => 5 × 8 => 40 years
