x=20

Answer 2

Correct question: One fourth of a number is increased by 7. Then the result is multiplied by 3. Thus, we obtain 36. Find the number.

Answer: 20

Step by step explanation:

Let the number be 'x'

.°. One fourth of the number = x/4

According to the question,

One fourth of a number is increased by 7 and the result is multiplied by 3 to get 36.

» ( x/4 + 7 ) × 3 = 36

x/4 + 7 = 36/3

x/4 + 7 = 12

x / 4 = 12 - 7

x / 4 = 5

x = 5 × 4

x = 20

Therefore,

Required number = x = 20
