Question

The value of 72 coins consisting of 50P ,25P, 10P, &5Pcoins is amounting to Rs. 22.40. The no. of 50P coins is as much as 25P coins & 5P coins together, the no. 25P coins = as much as 10P & 5P coins together. Find the no. of 50P coins.

Answer 1

Answer:

Solution

The correct option is C 720

The 50p, 25p and 10p coins are in the ratio 5:9:4.

Hence let the no. of coins be = 5x , 9x , 4x respectively

The total amount in the bag is = Rs.206

=> (0.50)(5x) + (0.25)(9x) + (0.10)(4x) = 206

= 2.5x + 2.25x + .4x = 206

= 5.15x = 206

= x =

206

5.15

∴

x = 40

=> No. of 50p coins = 5x 40 = 200

=> No. of 25p coins = 9x 40 = 360

=> No. of 10p coins = 4x 40 = 160

=> Total No. of coins in the bag = 200 + 360 + 160 = 720 coins
