Question

Three fourth of a number exceeds its one third by 15.Find the number

Answer 1

Answer:

The required value of x is 36

Step-by-step explanation :

Let the required number be x.

Three fourth of number = ( 3 / 4 )x

One third of number = ( 1 / 3 ) x

According to the question ;

3x / 4 = x / 3 + 15

⇒ 3x / 4 - x / 3 = 15

⇒ 9x - 4x / 12 = 15

⇒ 5x = 15 × 12

⇒ x = 180 / 5

⇒ x = 36

Hence, the required answer is 36.

Answer 2

3/4 x + 15 = 1/3x

15 = 1/3x - 3/4x

15 = 4x-9x/12

180 = -5x

X = -36
