Question

there are there are some 50 paise and some 25 paise coins in the back if the total number of the coins is 30 and their total value is 11 find the number of coins of each kind​

Answer 1

Step-by-step explanation:

Let 50 p coins be X.

So 25 p coins=30-X.

ATQ,X×50+(30-X)×25=11×100

or 50X+750-25X=1100

or 25X=1100-750=350

or X=350/25=14

No of 50 p coins=14

No of 25 p coins=30-14=16
