A’s monthly income is 10% more than that of B. B’s monthly income is 20% more than that of C. if the sum of the monthly income of A and B is Rs. 315000. what is the monthly income of C? Correct Answer 125000

Given :

A’s monthly income = B’s monthly income × 110%

B’s monthly income = Monthly income of C ×  120%

Sum of the monthly income of A and B = 315000 Rs.

Calculation:

Let income of C be 100

Income of B = 100 × 120% = 120

Income of A = 120 ×  110% = 132

A    :    B     :     C  

132 :  120  :  100          

33    :  30    :    25

A + B = 33 + 30 = 63 unit

63 unit = 315000 Rs

1 unit = 5000Rs

25 unit (income of C) = 25 × 5000

⇒  125000 Rs

∴ Monthly income of C is 125000.
