​

Answer 1

Answer:

2000 is reduced to 2400.

Answer 2

Answer:

Rs 2400 is more than Rs 2000 by 20%

Rs 2000 is less than Rs 2400 by 16.66%

Step-by-step explanation:

Difference between Rs 2400 and Rs 2000 = Rs 2400- Rs 2000 = Rs 400  

\therefore,  The per cent by which Rs 2,000 is less than Rs 2,400 is

400/2400 X 100=16.66% (Less with respect to 2400. Hence, 2400 will be in the denominator!)

Rs 2000 is less than Rs 2400 by 16.66%

Now,

therefore,  The per cent by which Rs 2,400 is more than Rs 2,000 is

400/2000 X 100 = 20% (More with respect to 2000. Hence, 2000 will be in the denominator!)

Rs 2400 is more than Rs 2000 by 20%

 Therefore, they are not the same.
