Best answer
Correct Answer - Option 2 : 15

Given

Ratio of 50 paise, Rs1 and Rs 2 coins = 10 : 3 : 1

Concept

1 Rs = 100 paise

Calculation

Total amount in the bag = 5000 paise (i.e 50 × 100

Let the number of 50 paise coins is 10 x, Rs. 1 coins are 3x and Rs 2 coins are x

According to question

50(10x) + 100(3x) + 200(x) = 5000

500x + 300x + 200x = 5000

1000x = 5000

x = 5

∴ One Rupees coins are 15 (i.e. 3 × 5)
