Question

(iii) I have some 20 paise coins and an equal
number of 10 paise coins. If the total
amount is $300, how many coins of each
denomination are there?​

Answer 1

Answer:

Let, x be number of 20 paise and 10 paise coin

So, 20x + 10x = 30000 paise

30x = 30000

x = 1000

So you have 1000 coins of each.
