Answer 1

✽ Question ✽

Two times a number is 100% increase in the number. If we take half the number what would be the decrease in percent?

✽ To find ✽

The decrease percent.

✽ Solution ✽

Let the number be x.

According to condition,

2x = x + 100% of x

→ 100% of x = 2x-x

→ 100% of x = x

So, 100% = x

Half of x

= 1/2 × x

= 1/2 × 100% {since, x = 100%}

= 50%

✽ Hence ✽

Half of the number is 50%.

✽ Therefore ✽

If we take half of the number, the percent of decrease would be 50%.

Hope this helps you.
