# What will be number

If 75/2% of a number is 900, then 125/2 % of the number will be:

- 1200
- 1350
- 1500
- 540

**Answer: (3) 1500**

**Explanation:-**

Let the number be X

If 75/2% of a number is 900.

Then, X x 75/2 x 100 = 900

3 X/8 = 900

3 X = 900 x 8

3 X = 7200

X = 7200/3

X = 2400

Then, 125/2% of 2400 = 2400 x 125/2 x 100

= 12 x 125

= 1500

Then 125/2% of the number will be 1500.

Hence, the correct answer is option (3) 1500.
