Answer 1

Answer:

Answer no. 4

Step-by-step explanation:

Let Suresh age be X and that of his mother be y.

so x+ y =89 ....(1)

and after 11 years his mother will be twice of his age. so y +11 = 2(X +11)

= y +11 = 2x + 22

= 2x - y= -11 .....(2)

after solving both equations X=26 and y=63. that is the answer
