Solution(By ExamCraze Team)

Let P, Q and R represent their respective monthly income
Then, we have
P + Q = (5050 × 2) = 10100.....(i)
Q + R = (6250 × 2) = 12500.....(ii)
P + R = (5200 × 2) = 10400.....(iii)
Adding (i), (ii) and (iii), we get
2 (P + Q + R) = 33000
⇒ P + Q + R = 16500
Subtracting (ii) from (iv), we get P = 4000
∴ P's monthly income = Rs. 4000
