Question

Rohit's mother gave him Rs.4xy^2 and his father gave him Rs. (5xy^2+3). Out of this total money, he spends Rs. (10-3xy^2) on his birthday party. How much money is left with him?

Answer 1

Answer:

The Amount received by Rohit's mom = 4xy^2

The Amount received by Rohit from his father = [5xy^2 +3]

The Amount received is =[4xy^2] + [5xy^2 +3]

=9xy^2 +3

amount left = 9xy^2 +3 - (10-3xy^2)

=12xy^2-7

Answer 2

Answer:

Total money with Rohit

=Rs {4xy^2+(5xy^2+3)}

=Rs( 5xy^2+4xy^2+3)

=Rs( 9xy^2+3)

Amount spent by Rohit

=Rs (10-3xy^2)

Money left with him=Total money − Amount spent

=Rs( 9xy^2+3)−Rs (10-3xy^2)

=Rs { 9xy^2+3−10-3xy^2}

=Rs{ 5xy^2−7}
