Explanation:

The monthly income of Shyama and Kamal => S + K = 28000 —(1)
Shyama’s income = x;
Kamal’s income = 28000 – x.
K = 120/100 * S —(2)
S’s new income = (28000 – x)*112.5/100
K’s new income = x * 125/100 (28000 – x)*112.5/100 = x * 125/100 x = 12000
New Income of Shyama = 125% of 12000 = 15000
