Three hikers A, B and C start on a trip with ₹ 50 each and agree to share the expenses equally. If at the end of the trip, A has ₹ 20 left with him, B ₹ 30 and ₹ 40, by how much amount must they settle their accounts?
Correct Answer: C must pay ₹ 10 to A
Explanation:
They start with total of (50 x 3) = ₹ 150 and they return after the trip with (20 + 30 + 40) = ₹ 90.
So, to settle their accounts, each person must have 90/3 = ₹ 30 with them,
Hence, C must pay ₹ 10 to A
