Question

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,

⇒ 13x – 7x = 12

⇒ 6x = 12

⇒ x = 2  ...[Dividing both sides by 6]

Hence, the required number is 2.
