Question

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

Answer 1

Let the number be '2x', so we have

1/2 (2x) - 1/5 (2x) = 15

[1/2 - 1/5] (2x) = 15

[5/10 - 2/10] (2x) = 15

3/10 (2x) = 15

3/5 x = 15

x = 15 (5/3)

x = 25
so your answer is 2x= 2×25=50
thank you,hope it helps

Answer 2

$\boxed{ \bf Hola \: user}$

Let the number be 2x

According to the question


$\frac{1}{2} (2x) - \frac{1}{5} (2x) = 15 \\ \\ = > x - \frac{2x}{5} = 15 \\ \\ = > 5x - 2x = 75 \\ \\ = > 3x = 75 \\ \\ = > \boxed{ \bf x = 25} \\ \\ \boxed{ \bf 2x = 2 \times 25 = 50}$
Hope this helps you ☺
