Question

An american man change 120 dollars for 43.680 naira.How much in naira will be get for 45 dollars.

Answer 1

First find the exchange rate:
43,680 naira ÷ 120 dollars = 364 naira per dollar.

Then multiply by 45:
45 × 364 = 16,380 naira.

So for $45 you would get 16,380 naira.

(If you actually meant 43.680 naira = 43.68 naira for $120, then the result would be 45 × (43.68 ÷ 120) = 16.38 naira.)
