Answer 2

Answer: The correct number is 40 .

Step-by-step explanation:

Let the number be x.

According to question if 75% of a number is added to the number itself then the result is 35% of 200

So, 75% of x = 75x/100 = 3x/4

Now we will find 35% of 200

35/100 x 200 = 70

Here the result is 70.

75% of a number i.e. 3x/4 is added to the number itself which is x then the result is 35%of 200 means 70.

So we can write that,

⇒$\frac{3x}{4} + x =70$

⇒$\frac{3x+4x}{4} =70$

⇒$\frac{7x}{4} =70$

⇒$7x= 280$

⇒$x =\frac{280}{7}$

⇒$x =40$

Hence, the number is 40.
