Question

The monthly income of shyama and kamal together is rs.28000. the income of shyama and kamal is increased by 25% and 12.5% respectively. the new income of kamal becomes 120% of the new salary of shyama. what is the new income of shyama?

Answer 1

Let shyama's income be 'x'

     Kamal's income be 'y'

x + y = 28,000 ⇒ y = 28,000-x

new incomes,

shyama's income = x + (x) 25%

kamal's income = y + (y) 12.5%

according to the question,

y + (y) 12.5% = { x + (x) 25%} 120%

1.125 y = (1.25 x ) 120%

1.125 y = {1.25( 28,000- y) } 120%

2.625 y = 42,000

y (Kamal's old Income ) = 16,000

kamal's new income = 18,000
