Question

A lady has 25 paise and 50 paise coins in her purse. If in all she has 80 coins totalling rs.25,how many coins of each kind does she have

Answer 1

Let the number of 25-paise coins be n.

Then the number of 50-paise coins will be 120-n

∴25n+50×(120−n)=50×100

or n=40

Hence number of 50-paise coins=120-40=80
