Question

if a number of which the half is greater than 1/5th of the number by 15 then the number is​

Answer 1

Answer:

50

Step-by-step explanation:

Let the number be x

Given that half of x is greater than (1/5) of x by 15.

Half of x = x/2

(1/5) of x =x/5

In mathematical expression the given statement can be written as

(x/2)-(x/5) = 15

Taking common denominator we get,

(5x-2x)/10 = 15

5x-2x = 150

3x = 150

x = 50

You can check it out by substituting the value of x and you will get the same answer.

Hope this helps

Answer 2

Let the required number be X .

According to the question -

" number of which the half is greater than 1/5th of the number by 15 " -

Half of the required number

=> X / 2

This is greater than 1/5 th of the number by 15

=> This is equal to ( x / 5 ) + 15

So , we can state the following -

( x / 2 ) = ( x / 5 ) + 15

=> ( x / 2 ) - ( x / 5 ) = 15

=> (5x - 2x ) = 150

=> 3x = 150

=> x = 50

Hence the required number is 50 .....
