Detailed Solution

Concept: Suppose Seema's age is

x

.
Then Sudesh'w age is

2 x

.
If 6 years are subtracted from Seema's age we get

x - 6

and if 4 years are added to Sudesh's age we get

2 x + 4

So we are given that

2 x + 4 = 4 (x - 6) = > 2 x + 4 = 4 x - 24

= > 4 x - 2 x = 4 + 24

= > 2 x = 28

= > x = 14

=> Sudesh' age

= 2 x = 28

So, the current ages of Seema and Sudesh are 14 years and 28 years.
So, 3 years ago Seema was 11 years and Sudesh was 25 years
Hence, the correct Option is (1) 25 & 11.
