Q5. An amount of money is to be distributed among A, B and C in the ratio 3 : 1 : 5. The difference between B’s and C’s share is Rs. 3600. What is the total of A’s and B’s share?
Rs. 5400
Rs. 3600
Rs. 2700
Rs. 1800
Rs. 2100
Solution:
Let the common multiple be ‘x’
Now,
5x – x = 3600
∴ 4x = 3600 ⇒ x= 900
A’s share = 3x = 3 × 900 = 2700
B’s share = x = 900
A’s share + B’s share
= 2700 + 900
= 3600
