A sum of Rupees 110 is made of Rupees 2, Rupees 1 and 50 paise coins in the ratio 1 : 2 : 3 respectively. How many 50 paise coins are there?
A20
B60
C40
D80
Answer & Solution
Correct answer: B. 60
1. Let the counts be x, 2x and 3x. Value = 2x + 1(2x) + 0.5(3x) = 2x + 2x + 1.5x = 5.5x.
2. 5.5x = 110, so x = 20.
3. Number of 50 paise coins = 3x = 60.
