Answer:
Rushbu exchanges 300 USD at the buying rate of NRs 119.25, so she will receive:
300 x 119.25 = NRs 35775
After allowing a 10% discount, Rushbu will need to pay:
35000 - (10/100 x 35000) = NRs 31500
Including 13% VAT, Rushbu will need to pay:
31500 + (13/100 x 31500) = NRs 35655
Since Rushbu received NRs 35,775 after exchanging her 300 USD, she will have enough Nepali currency to buy the television, even after accounting for the discount and VAT.
Therefore, Rushbu will have enough money to buy the television, and she will have NRs 120 less than she received from exchanging her 300 USD, but that does not affect her buying capacity in this case.
