3.The salary of Sheela is increased by 6.5%. If her present salary is 6390, find her salary
before the increment ... i need easy step by step explanation..​

Answer 1

Let her original salary be ₹ x.

So, new salary = ₹ (x + 6.5% of x)

= ₹ (x + 6.5x/100)

= ₹ 106.5x/100

According to condition,

106.5x/100 = 6390

or, 1065x/1000 = 6390

or, 1065x = 6390×1000

or, 1065x = 6390000

or, x = 6390000/1065

or, x = 6000

Original salary = ₹ x = ₹ 6000

Hence, her salary before the increment was ₹ 6000.
