Question

8. Kanwar has Rs 34 in 50-paise and 25-paise
coins. If the number of 25-paise coins is
twice the number of 50-paise coins, how
many coins of each kind does he have ?​

Answer 1

let 50 paise coin be x =50 ×X=50x

25 paise coin =2x=25×2X=50X

we have to convert rupees 34 into paise=3400 paise

3400=50x +50x

3400=100x

x=34

50 paise coin =34 and 25 paise coin=68

we can prove it =34×50=1700 paise

68×25=1700 paise

=3400 paise = 34 rupees
