In a bag, there are coins of 25 p, 10 p and 5 p in the ratio of 1:2:3. If there are Rs. 30 in all, how many 5 p coins are there? | [
"150",
"176",
"154",
"717"
] | A | Let the number of 25 p, 10 p and 5 p coins be x, 2x and 3x respectively.
Then, sum of their values
= [25x/100 + (10 * 2x)/100 + (5 * 3x)/100]
= Rs. 60x/100
60x/100 = 30 => x = 50.
Hence, the number of 5 p coins = 3 * 50 = 150.
