(5) None of these​

Answer 1

Answer:

18000

Step-by-step explanation:

reemas monthly income = 90%*Soni's income

ie. R=90%*S

Preeti monthly income= 125% reemas income

ie.P= 125%R

P-S = 2500

Substituting the values of R and P in the above equation.

(125%R) - S=2500

((125/100)*(90/100)) - S = 2500

on solving , S = 20000

therefore reemas monthly income = 90% of S

= 90% * 20000

= 18000
