Rohan's age after 3 years =(x+3) years
After 3 years the age of Rohan's mother=(x+26+3)years=(x+29) years
It is given that after 3 years from now, the product of Rohan's and his mother's ages will be 360 years
∴(x+3)(x+29)=360⇒x

+32x−273=0....answer
This is the required equation.

∴x=−39 and x=7
∴x=7.......(∵ x can not be negative)
∴ Mother's present age=7+26=33...
