Question

2. Arjun has a piggy bank where he collected only
50 p coins and one-rupee coins. It contained 4
times as many 50 p coins as one-rupee coins. If
the total amount of money in the piggy bank is
₹111, find the number of each kind of coin in it.​

Answer 1

Answer:

Let's say 50p coins are x

Rs.1 coins are y

We know that

2 50p coins = 1 one rupee coin

Thus, 2x = y.........(1)

Total amount collected = ₹111

Thus,

x + y = 111

Since, 2x = y.............from(1)

x + 2x = 111

3x = 111

x = 111/3

Thus, x = 37

2x= 74

Arjun has 37 50 p coins and 74 one rupee coins
