Question

17. Sumitra has 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 she have?
​

Answer 1

Answer:

25 paise coins = 68 coins

Answer 2

Answer:

34 - 50 paise       68 - 25 paise

Step-by-step explanation:

let the unknown number of 50 paise be 50x

the unknown number of 25 paise be 25y

given that

the number of 25 paise is twice that of 50 paise           25y=50x

50x+50x=3400

100x=3400

x=34

the number of 50 paise coins is 34

the number of 25 paise is double of 50 paise so 68
