According to the exchange rate of Nepal Rastra Bank on the date of 11/25/2025, the buying rate and selling rate of 1 US dollar were NRs. 142.48 and NRs. 143.08 respectively. a) Among the buying rate…

Solution

a) Exchange direction

When exchanging US dollars (USD) into Nepalese rupees (NRs), the bank buys USD and sells NRs. Therefore, the buying rate (NRs. 142.48) is used.

b) Initial exchange for 3000 USD

Using the buying rate: $$3000\text{ USD}\times 142.48\text{ NRs./USD}=426,440\text{ NRs.}$$ Answer: NRs. 426,440

c) Rates after 0.5% devaluation

A 0.5% devaluation means the NRs. weakens by 0.5%, so the exchange rates increase by 0.5%: $$\text{New buying rate}=142.48\times (1+0.005)=143.15\text{ NRs./USD}$$ $$\text{New selling rate}=143.08\times (1+0.005)=143.76\text{ NRs./USD}$$

d) Gain after devaluation

The tourist gains more NRs. per USD after devaluation. The difference per USD is: $$143.15-142.48=0.67\text{ NRs./USD}$$ For 3000 USD: $$0.67\times 3000=2010\text{ NRs.}$$ However, the question likely expects the total gain in NRs. when exchanging at the new rate: $$3000\times 143.15=429,450\text{ NRs.}$$ $$\text{Gain}=429,450-426,440=3,010\text{ NRs.}$$ Clarification: The correct interpretation (as per standard exchange rate adjustments) is that the buying rate increases by 0.5%, leading to a higher NRs. per USD. The gain per USD is: $$(143.15-142.48)\times 3000=1,710\text{ NRs.}$$ Answer: NRs. 1,710 (gain per USD × total USD).
