Question

a man has only 20 paise coins and 25 paise coins in his first if he has 50 coins in all totalling rupees 11.25 how many coins of each kind does he have

Answer 1

let we have x number of 20paisa coin
and 25paisa coin = y
then,
x+y = 50
=> x = 50-y
and,
20x +25y = 1125 paisa

by putting the value of x
=>20(50-y) +25y = 1125
=>1000+5y =1125
=>5y = 125
=> y = 25
hence ,
we have 50 coins of 25 paisa
and also 25 coins of 20 paisa
