Question

by what percent is ₹2000less than ₹2400.is it the same as the percent by which₹2400 is more than ₹2000​

Answer 1

Step-by-step explanation:

Case I

Here 2000 2400.

i.e. 2400 is reduced to 2000.

Decrease = 2400 - 2000 = 400

This Decrease % = x 100% = 50% = 160%

400 2400

Thus, Decrease % 16 2/3

Case II

2000 is reduced to 2400.

Increase = 2400 - 2000 = 400

Decrease% = 400 2000 x 100% = 20%

Thus, Decrease% = 20%

Obviously, they are not same.

Answer 2

Answer:

To Find:- % of difference

Solution:-

First of all

difference between 2400 & 2000 is

2400-2000=400

and now, we've to find what percentage of 2400 is 400

by using the formula

$\frac{400}{2400} \times1 00 \\ \\ \frac{400}{24} = \frac{200}{12} = 16.67$

therefore 16.67% of 2400=400

Now,is is the same % of increase

for,that

2400-2000=400

what% of 2000 is 400

if it's the same,then it's correct

$\frac{400}{2000} \times 100 \\ \frac{4}{20} \times 100 \\ \frac{400}{20} = \frac{40}{2} \\ = 20$

therefore 20% of 2000 is 400

hence, both are of different percentage
