Question

When 125 is subtracted from a number is reduced to its 37.5% what is 25% of this number

Answer 1

Answer:

50

Step-by-step explanation:

We will analyze the question as follows :

100% - 37.5% = 62.5%

This is what has been subtracted from the original number to reduce it to 37.5%.

From this we can get the original number.

This implies that :

62.5% = 125

100% =?

By cross multiplication we have :

100/62.5 × 125 = 200

We need 25% of 200.

We get this by :

25/100 × 200 = 50

So 25% of the number is 50.
