Question

A lady has only 20- paisa coins and 25 - paisa coins in her purse . If she has 50 coins in all totaling Rs 11.50 how many coins of each kind does she have

Answer 1

let the number of 20 paisa coins be x and 25 paisa coins be y

so , 20x +25y = 1150 (1) ( convering values in paisa)

and x +y = 50 (2)

so x = 50 - y 

putting the value of x in equation (1)

so, 20(50 - y) + 25y = 1150

1000 - 20y + 25y = 1150

5y = 1150 -1000

5y = 150

y = 30

so the number of coins 25 paisa is 30 now putting this value of y in eq 2 

x + y = 50

x + 30= 50

and y =20
