Question

A bag contains 25 paisa and 50-paisa coins whose total value is ₹ 30. If the number of
25-paisa coins is four times that of 50-Paisa coins, find the number of each type of coins.​

Answer 1

Answer:

let the 50paise be x and 25paise be 4x

50*x+25*4x=3000

50x+100x=3000

150x=3000

x=20,then

total coins of 25 is 20*4=80

Answer 2

Let us assume that

Number of 25p coins = 8x

Number of 50p coins = 4x

Number of Rs. 1 coins = 2x

As per the given condition

8x + 4x + 2x = 840

14x = 840

x = 840/14

x = 60

Hence,

Amount of 25p coin = 60 × 8 × 25 = 12000 paisa = Rs. 120

Amount of 50p coin = 60 × 4 × 50 = 12000 paisa = Rs. 120

Amount of Rs. 1 coin = 60 × 2 × 1 = Rs. 120

On summing up the above-obtained values the total amount in the bag is Rs120+Rs120 +Rs 120 = Rs360
