Percentage (4)

30% income of P is equal to 1.5% income of Q and 10% income of Q is equal to 20% income of R. If the income of R is Rs 4000; then the total income of P, Q and R is ..................










Answer

(30/100)P = (1.5/100)Q -----------(1)

(10/100)Q = (20/100)R  -----------(2)

multiply (2) by 0 .15.

(1.5/100)Q = (3/100)R ------------(3)

compare (1) and (3), we have

(30/100)P = (1.5/100)Q = (3/100)R

But R = 4000

So, Q = (3/1.5)R = 2 x 4000 = 8000

P = (3/30) x R = (3/30) x 4000 = 400

So, P + Q + R = 400 + 8000 + 4000 = 12400
