The average monthly income of P and Q is Rs. 20,000. The average monthly income of Q and R is Rs. 40,000. Monthly income of R is how much more than monthly income of P? Correct Answer Rs. 40,000

The average monthly income of P and Q is Rs.20,000

The average monthly income of Q and R is Rs.40,000

Calculation:

(P + Q)/2 = 20000

(Q + R)/2 = 40000

⇒ Q + R = 80000  -(2)

Equation (2) - (1)

⇒ R - P = 40000

∴ Monthly income of R  is 40000 more than monthly income of P
