Question

The difference between 90% and 75% of a number is 225 .Then find out 82% of the number ?​

Answer 1

Answer:

1230

Step-by-step explanation:

let the number be x.

by given condition,

90% * x - 75%*x = 225

9x/10 - 3x/4 = 225

(18x - 15x) / 20 = 225

3x = 225 * 20

3x = 4500

x = 1500

82% of x = 82/100 * x

= 82 / 100  *  1500

= 82 * 15

= 1230

Answer 2

Given,

For a certain number;

The difference between 90% and 75% of that number = 225

To find,

The value of 82% of that number.

Solution,

We can simply solve this mathematical problem using the following process:

Let us assume that the certain number is x.

Now, according to the question;

The difference between 90% and 75% of that number = 225

=> (90% of x) - (75% of X) = 225

=> (90/100 × x) - (75/100 × x) = 225

=> x/100 × (90-75) = 225

=> x/100 × 15 = 225

=> x = (225 × 100)/15

=> x = 1500

=> the certain number = 1500

Now,

The value of 82% of x

= 82/100 × 1500

= 1230

Hence, the value of 82% of the given certain number is equal to 1230.
