Answer»

Let salary of Ananya be ‘4x’ and salary of Krish be ‘5x’

⇒ According to the condition GIVEN in the problem,

$(\frac{{4x + 5000}}{{5x + 5000}} = \frac{{67}}{{71}})$

⇒ 71(4x + 5000) = 67(5x + 5000)

⇒ 284x + 355000 = 335x + 335000

⇒ 51x = 20000

⇒ x = RS. 392.15

∴ Krish’s salary = Rs. 1960.75
