Asked by asjad

a lady has only 20 paisa coins and 25 paisa coins in her purse if she has 50 coins in totalling
rupees 11.50 how many coins of each kind does she have
Answered by Reiny
number of 20 paisa coins --- x
number of 25 paisa coins --- 50-x

20x + 25(50-x) = 1150
20x + 1250 - 25x = 1150
-5x = -100
x = 20

so she has 20 of the 20paisa and 30 of the 25 paisa coins

check:
20+30 = 50 , check!
20(20) + 25(30) = 1150 , check!
