Question

a bag contains rs 112 in the form of 1 rupee, 50 paise and 10 paise coins in the ratio 3:8:10 what is the number of 50 paise coins

Answer 1

Answer:

Number of 50 paise coins = 112

Step-by-step explanation:

Total amount in the bag = 112 Rs.

Let the common ratio is x

Then the no. of 1 Rs. = 3x

No. of 50 paise (0.5 Rs.) = 8x

No. of 10 paise (0.1 Rs.) = 10x

According to the queston

3x × 1 + 8x × 0.5 + 10x × 0.1 = 112

or, 3x + 4x + x = 112

or, 8x = 112

or, x = 112/8 = 14

Therefore, the number of 50 paise coins = 8x = 8 × 14 = 112
