Question

The monthly income of santhosh and vignesh is Rs. 62500. The income of santhosh and vignesh increased to 20 percent and 15 percent respectively. New income of vignesh is Rs. 1375 more than that of santhosh. What is the new income of vignesh?

Answer 1

Let the income of Santhosh and Vignesh be S and V,

The monthly income of Santhosh and Vignesh = 62500

S + V = 62500

Santhosh’s income = x; Vignesh’s income = 62500 – x

New income of V = New income of S + 1375

V’s new income = (62500 – x)*115/100

S’s new income = x * 120/100

(62500 – x)* (115/100) = x * (120/100) + 1375

(7187500 – 115x)/100 = (120x/100) + 1375

(7187500 – 115x)/100 = (120x + 137500)/100

(7187500 – 115x) = (120x + 137500)

7187500 – 137500 = 115x + 120x

7050000 = 235x

Santhosh’s income X = (7050000/235) = 30000

Vignesh’s income = 62500 – x = 32500

New Income of Vignesh = 32500*(115/100) = Rs. 37375
