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
2A=11N-1
Put value of A from equation 1
4+2N2= 11N-1
2N2-11N+5=0
(2N-1)(N-5)=0
N=5, A=2+25=27

hi
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.
2x2-x+4=10x+1
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.
