Answer 1

let Mary's sallary be rs. x. so Jack's will be (x-1/5)rs. and Thomas's sallary will be( x-1/5)-1/4=(x-9/20)rs
Robert's sallary=3600=(x-9/20)-1/10 x=rs 3600.55

Answer 2

Answer:

Let Mary's salary be rs. x. so Jack's will be (x-1/5)rs. and

According to the question,

Thomas's salary will be( x - 1/5) - 1/4= Rs (x-9/20)

Robert's salary = 3600 = ( x - 9/20) - 1/10 x = Rs 3600.55.

on solving the above equation you will get the salary of Mary.
