There are some 25 paise coins and some 50 paise coins in a bag.The total number of coins is 140 and the amount in the bag is 5000 paise . find the number of coins of each value in the bag.

Answers (1)

Assume the number of 25 paise coins, 50 paise coins are x, y respectively.

ATQ

x + y = 140..(i)

25x + 50 y = 5000

x + 2y = 200...(ii)

Equation (ii) - Equation (i)

x + 2y -x - y = 200 - 140

y = 60

x = 80 

Hence the number of 25 paise coins, 50 paise coins are 80, 60 respectively.
