Question

Rohan's mother gave him rs. 3xy2 and his father gave him rs. 5(xy2 + 2). Out of this total money, he spent rs. (10 - 3xy2 ) on his birthday party. How much money is left with him?

Answer 1

Step-by-step explanation:

total money received = 3xy2 + 5(xy2+2)

= 8xy2 + 10

Answer 2

Given:

• Amount given by mother = $3xy^{2}$

• Amount given by father = $5xy^{2} +2$

• Amount spent by Rohan = $Rs. \: 10-3xy^{2}$

To Find:

Amount left with Rohan.

Solution:

According to the question,

Total money Rohan got = $3xy^{2} +5xy^{2} +10$

$\implies 8xy^{2} +10$

Now,

Money spent by Rohan = $10-3xy^{2}$

Therefore,

Money left with Rohan = $8xy^{2} +10 -(10-3xy^{2} )$

$\implies 8xy^{2} +10-10+3xy^{2}\\:\implies \boxed{Rs. \: 11xy^{2} }$

Thus, Rs. 11xy² is left with Rohan.
