Question

By what % is rupees 2,000 less than rupees 2,400 ? Is it the same as the % by which rupees 2,400 is more than rupees 2,000?

Answer 1

Answer:

2000 is 16.67% less than 2400.

2400 is 20% more than 2000.

So no, the numbers are not the same!

Step-by-step explanation:

2000 is 400 less than 2400, and 400 is

400/2400 × 100% = 16.67%

of 2400.

So 2000 is 16.67% less than 2400.

That is, 2000 = (100% - 16.67%) of 2400 = 83.33% of 2400.

2400 is 400 more than 2000, and 400 is

400/2000 × 100% = 20%

of 2000.

So 2400 is 20% more than 2000.

That is, 2400 = (100% + 20%) of 2000 = 120% of 2000.
