Question

5 subtract from one third of a number gives 12 find the number

Answer 1

Let's assume the require number as x

One-Third of the number

= 1 / 3 × x = x / 3

According to Question,

x / 3 - 5 = 12

⇒ (x - 15) / 3 = 12

⇒ x - 15 = 12 × 3

⇒ x - 15 = 36

⇒ x = 36 + 15

⇒ x = 51

As, the required number is x

Hence, the required number is 51

Answer 2

Hey there... Let the unknown number be =x

One third of the number=1/3

1/3x-5=12

Lowest common multiple =12

You'll multiply through by 12

12x1/3x-5x12=12x12

4x-60=144

4x=204

X=204/4

X=51
