Question

In a bag there are 1 rupess 50 paise 25 paise coins . total number of coins are 540 . if the ratio of their rate is 5 : 4 :1

Answer 1

We first convert the rates to the same units.

1 paise = 0.01 Rupees

1 rupee =? Paise

1/0.01 = 100 paise

Sum of the ratios is :

5 + 4 + 1 = 10

1 Rupees coin = 5/10 × 540 = 270 coins

50 paise coins = 4/10 × 540 = 216 coins

25 paise coins = 1/10 × 540 = 54 coins

Their total value is :

(270 × 100) + (216 × 50) + (54 × 25) = 39150 paise

Converting this to Rupees :

39150 × 0.01 = 391.5 Rupees
