Dear Jayati

let Asha age=A and Nisha age= N

A=2 + N2 .......(1)

present difference in age A-N years , so nisha will be of his mom's age after A-N years

After A-N years his mother's age = A+A-N = 2A-N

Now fron question

2A-N = 10N -1


Put value of A from equation 1

4+2N2= 11N-1



N=5, A=2+25=27


All the best.

let nishas present age be x.

then ashas age is 2+x2.

then nishas age after x2 -x+2 yrs will be 2+x2.

therefore ashas age after x2-x+2 will be 2x2-x+4yrs.


solving this we get x as 5.

there fore nishas age is 5 and that of asha is 27

plzz approve if you like the answer.
