Q. 70

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

Answer :

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 number is 2.
