Question

Anu has only 10 paise and 50 paise coins in her purse. If the total number of coins is 17 and their total value is ₹4.50,find the number of each type of coins

Answer 1

Step-by-step explanation:

total number of coins is 17

let number of 10 paise coins = a

then number of 50 paise coins = 17-a

given,

a×10 + (17-a)×50 = 450

=> 10a + 850 -50a = 450

=> 40a = 400

=> a = 400/40 = 10

number of 10 paise coins = a = 10

and number of 50 paise coins = 17-a= 17-10 = 7
