There are 25 p, 10 p, and 5 p coins in a bag in the ratio of 1 : 2 : 3. How many 5 p coins are there in total if there are Rs. 30?
A. 50 B. 100 C. 150 D. 200
Explanation: Let x, 2x, and 3x be the number of 25 p, 10 p, and 5 p coins, respectively.The aggregate of their values is thus Rs. 25x/100 + Rs. 10x/2x/100 + Rs. 5x/3x/100 = Rs. 60x/100.x = 30 x 100/60 = 50, 60x/100 = 30.As a result, the number of 5 p coins is equal to (3 x 50) = 150.
