Question

If 1/4 of a number is added to 1/3 of that number, result is 15 greater than half of that number. Find the number

Answer 1

Answer:

180

Step-by-step explanation:

STEP 1 : Define x

Let the number be x

STEP 2: Form equation

x/4 + x/3 = x/2 + 15

STEP 3: Solve x

7x/12 = x/2 + 15

7x/12 - x/2 = 15

1x/12 = 15

x = 180

STEP 4: Find the number

Number = x = 180

Answer: The number is 180

Answer 2

Answer: 180

Step-by-step explanation:

Let the number be x

According to question.

x/4 +x/3 = 15 + x/2

x/4+ x/3 - x/2 = 15

Taking common factor,

3x/12 + 4x/12 - 6x/12 = 15

x/12 = 15.

x= 15×12 = 180
