Question

a man has rupees 21 in the form of 50 paise and 25 paise coins if the total number of coins are 52 find the number of coins of each type

Answer 1

Let 50p = x and 25p = 25 - x

So, 50p = 50x and 25p = 25 X (52 - x)

50x + 1300 - 25x = 2100

50x - 25x = 2100 - 1300

25x = 800

x = 800/25 = 32

50 paise coin = 32

25 paise coin = 52 - 32 = 20
