Question

Answer 1

Answer:

45/100×x-20/100×x

200

Answer 2

40% of the number is 200.

Given:

Difference=125

To find:

40% of the number

Solution:

Let the number be X.

We know that the difference between 20% of X and 45% of X is given as 125.

So, 20% of X=20/100×X

=20X/100

Similarly, 45% of X=45/100×X

=45X/100

Now, their difference is as follows-

45X/100-20X/100=125

(45X-20X)/100=125

25X=125×100

X=125×4

X=500

We will now calculate 40% of this number.

So, 40% of X=40/100×500

=40×5

=200

Therefore, 40% of the number is 200.
