Asked by admin @ in Math viewed by 297 People
The average monthly income of P and Q is rs 5050, Q and R is 6250, and P and R is 5200. Find the monthly income of P ?
Answered by admin @
║⊕ANSWER⊕║
Let P, Q and R represent their respective monthly incomes. Then, we have:
P + Q = (5050 x 2) = 10100 .... (i)
Q + R = (6250 x 2) = 12500 .... (ii)
P + R = (5200 x 2) = 10400 .... (iii)
Adding (i), (ii) and (iii), we get: 2(P + Q + R) = 33000
or
P + Q + R = 16500 .... (iv)
Subtracting (ii) from (iv), we get P = 4000.
P's monthly income = Rs. 4000.
