Question

8. Aravind has a kiddy bank. It is full of one-rupee and fifty paise coins. It contains 3 times as many fifty paise coins as one rupee coins. The total amount of the money in the bank is 35. How many coins of each kind are there in the bank? ​

Answer 1

Answer:

There are 14 one rupee coins. There are 42 fifty paise coins.

Step-by-step explanation:

One rupee coins: Z

Fifty paise coins: Y

                          : 3Z

(Z x 100) + (3Z x 50) = 3500

100Z + 150Z = 3500

250Z = 3500

Z = 3500/250

  = 14

There are 14 one rupee coins.

14 x 3 = 42

There are 42 fifty paise coins.
