Question 91

150 has been divided into two parts such that twice the first part is equal to the second part. Find the parts.

Answer 1

Let one part be x, then another part will be 2x as the second part is twice the first part.
Since 150 has been divided into above two parts.
According to the question,
x + 2x = 150
$\Rightarrow 3x=150\Rightarrow \frac{3x}{3}=\frac{150}{3}\left[dividingbothsidesby3\right]\Rightarrow x=50$
Hence, the first part is 50 and the second part is $2\times 50=100.$
