Question

7. Pratap paid 20% of his salary as income tax. If he is left with 8,400 after paying the tax, find his salary.​

Answer 1

Answer:

Rs 10500

Step-by-step explanation:

Let Pratap's salary be Rs x.

So, tax paid = 20% of Rs x = Rs x/5

So, Salary left after paying tax = Rs (x - x/5) = Rs 4x/5

So, 4x/5 = 8400

Or, x = 8400 x 5/4 =Rs 10500

Answer 2

Answer: 10500

Let Pratap's salary =Rs.x

Money left with him  after paying  the tax =8400

Percentage of salary he paid =20%

Percentage of salary is left with= 100%−20%

=80%

Therefore,

80% of Rs.x=8400

10080×x=8400

x=808400×100

x=10500

Thus,

Pratap's salary =Rs.x=10500

Hence, this is the answer.
