heya friend!!☺☺
here's your answer!!☺☺
let 25 paisa coins = x
so 1rs coins = 3s
so 50 paisa coins = 220 - x- 3x = 220 - 4x
so total amount = 160 rs
so x/4 + (220-4x)/2 + 3x = 160
or x+ 440 - 8x + 12x = 640
or 5x = 200
x= 40
so 50 paisa coins = (220 - 4*40) = 220 -160 = 60
hence the number of 50 paise coins is 60..
hope it helps you!!☺☺
