Question

A man got 12% increase in his salary. If his new salary is 61600. His original salary is

54,000
X 55,000
56,500
X57,500​

Answer 1

Answer:

55,000

Step-by-step explanation:

x+12%x=61600

x+12x/100=61600

112x/100=61600

112x=6160000

x=6160000/112

x=55,000

Answer 2

let the original salary be x

then,

$x + \frac{x}{100} \times 12 = 61600$

$\frac{100x + 12x}{100} = 61600$

$112x = 61600 \times 100$

$x = \frac{61600 \times 100}{112}$

$x = 55000$

so the original salary is 55000
