Question

Raju salary was first increased by 10 percent then decreased by 20 percent if the latest salary is 17600 then find his original salary

Answer 1

Raju's original salary was 20000

Explanation:

let x be the original salary

first salary was increased by 10 percent = 10% of x = x * 10/100 = x/10

then salary was decreased by 20 percent =

20% of x = x * 20/100 = x/5

according to the question,

x + x/10 - x/5 = 17600

10x + x - 2x / 10 = 17600

9x / 10 = 17600

9x = 17600 * 10

9x = 176000

x = 176000/9 = 20000

thus, Raju's original salary was 20000
