Question

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

Answer 1

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 = ₹ (10 – 3xy²)

∴ After spending, Rohan has left money.
