Question

Two times a number is a 100% increase in the number. If we take half the number what would be the decrease in per cent? 2. By what per cent is rs 2,000 less than rs 2,400? Is it the same as the per cent by which rs 2,400 is more than rs 2,000?

Answer 1

Answer:

1) 50%

2) They are different

Step-by-step explanation:

1) If we take half the number, decrease will be 50%

2) ((2400-2000)/ 2400) * 100 = 50/3 %

   ((2400-2000)/ 2000) * 100 = 20%

Both are different!
