Question

A piggy bank contains coins consisting of 10c, 25c and P1 coins. The number of P1 coins is 5 more than the number of 10c coins. The number of 25c coins is thrice the number of 10c coins. If there are 50 coins in the piggy bank, how many P1 coins are there?

Answer 1

Answer:

There are 14 P1 coins in the Piggy Bank

Step-by-step explanation:

Let us Suppose no. of 10c coins be x

No. of P1 coins = y = 5 + x

No. of 25c coins = z = 3*x

Total coins in the Piggy Bank = 50

According to the given Conditions,

50 = x + y + z

50 = x + 5 + x + 3*x

50 = 5 + 5x

Dividing the equation by 5,

10 = 1 + x

x = 10 -1

x = 9   [therefore, No. of 10c coins = 9]

No. of P1 coins = 5 + x  

                         = 5 + 9

                         = 14
