Question

The salary of a man is reduced by 25%. How much % should it be increased to bring it at par with his previous salary?

Answer 1

Assuming his initial salary is 1000$ then the 10% cut reduces that salary to 900$. Expressed in an equation it looks like this:

1000∗0.9=9001000∗0.9=900

Remember that you multiply with the remainder of your cut. If you’d multiply a thousand with 10% (= 0.1) then you’d get the amount you want to subtract from the thousand. But you want the remainder, so you multiply with 1–0.1=0.91–0.1=0.9.

Now, in order to calculate the percentage that you need to get the 900$ back to a full thousand, you divide both sides by 0.9 like so:

1000=900/0.91000=900/0.9

This equation simply says that a thousand is equal to 900 divided by 0.9 and it’s rather easy to agree on that, right? But here the 900 is divided. What we want is a multiplication because what we seek is a percentage to multiply our 900 with.

Well, 0.9 is nine tenths: 910910

So, simply take the inverse of 910910 and change the division to a multiplication:

1000=900∗1091000=900∗109

You’re done.

109109 in decimal is a periodic 1.111.11 and that’s your percentage, a periodic 11%.

Answer 2

Answer:

Step-by-step explanation:

Let’s say his salary is 100 Rs, so 25% will be cut, which is Rs 25. Now his salary is Rs 75. He needs Rs 25 more to make it equal to his previous salary. 33.3% of 75 is 25. So according to me 33.3% is the correct answer...
