Question 70

Seven times a number is 12 less than thirteen times the same number. Find the number.

Answer 1

Let the number be x.
Then, seven times of this number = 7x and thirteen times of this number = 13x.
According to the question,
$\Rightarrow 13x-7x=12\Rightarrow 6x=12\Rightarrow x=2$
Hence, the required number is 2.
