The average monthly income of A and B is ₹5,050, the average monthly income of B and C is ₹6,250, and the average monthly income of A and C is ₹5,200. What is the sum of the monthly incomes (in ₹) of A, B and C?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 16500.
A + B = 5050 × 2 = 10100
B + C = 6250 × 2 = 12500
A + C = 5200 × 2 = 10400
⇒ (A + B) + (B + C) + (A + C) = 10100 + 12500 + 10400
⇒ 2A + 2B + 2C = 33000
⇒ A + B + C = 16500
