Question

If 30% of a number is 90, what is 50% of the same number?​

Answer 1

50% of the same number is 16.66.

Step-by-step explanation:

We are told that 30% of a number is 90.

Let the number be x

Solution:

Then,  30% of a number is 90:

30× x ÷100= 90

3x= 900

x= 300

Now, since we know that the number is 300, we can find its 50% value.

50% of 300

50× 100÷300

50÷3

16.66

Result

Thus, 50% of the same number is 16.66.

Answer 2

Answer:

50% of the same number = 150

Explanation:

Given,

30% of a number is 90

To find,

The 50% of the same number

Solution:

Let 'x' be the number such that 30% of it is 90

30% of x = 90

$\frac{30x}{100} = 90$

$x = \frac{90X100}{30}$

x = 300

Hence, the number is 300.

To find 50% of 300

50% of 300 = $\frac{50}{100}X300$

= 150

∴50% of the same number = 150
