Answer 1

Answer:= Rs 17200 ....ans.

Step-by-step explanation:

let monthly income of C = x

.... .... .... .... B = x×80% = 4x/5

.... .... .... .... A = 4x/5×75%

= 4x/5×3/4

= 3x/5

it is given that A's monthly income is =

12900

so, we can write as,

3x/5 = 12900

x = 12900×5/3

x = 21500

so, C's income = Rs 21500 ....ans.

and B's income = 4(21500)/5

= Rs 17200 ....ans.
