Answer»

66240 is answer

First we have to ARRANGE in a single ratio line to A:B:C

A:B=15:16,B:C=17:18

If value of B is 17 then value of A=?

15/16=A/17

Then on solving A=15×17/16

A=15.937

So,A:B:C=15.937:17:18

Now,by adding 15.937x + 17X + 18x=50.9375x

Which is equal to 187450

So,x=187450/50.9375=3680

Then C monthly INCOME = 18x

18x=18×3680=66240
