The ratio of incomes of P and Q is 1 : 2. Ratio of income of Q and R is 3 : 2. If one-third of P's income is Rs. 4400 less than the half of P's income, then what is the Q's income ?

Rs. 52800

                 P  :  Q  :  R

Incomes     1  :  2

                         3  :  2

                 3  :  6  :  2                                    

Given, one-third of P's income is Rs. 4400 less than the half of P's income

⇒ R = \(\frac{3R}{2}\) - 440

⇒ R = 880

Q's income = 6R = 6 x 880 = Rs. 5280
