Solution

Given, amount given to Rohan by his mother =3xy2
and amount given to Rohan by his father = 5(xy2+2)
Total amount Rohan have =[(3xy2)+(5xy2+10)]=[3xy2+5xy2+10]
= ₹(8xy2+10)
Total amount spent by Rohan = ₹(103xy2)
After spending, money left with Rohan
=[(8xy2+10)(103xy2)]=8xy2+1010+3xy2=8xy2+3xy2+1010=11xy2
