Question

add 15 to a number,then multiply the result by 3. The answer is the same as subtracting 4 from the number and multiplying the result by 5 .find the number

Answer 1

Answer:

The required number is 32.5

Step-by-step explanation:

Let the number be x,

Then, according to the Question,

(x + 15) × 3 = (x - 4) × 5

3(x + 15) = 5(x - 4)

3x + 45 = 5x - 20

5x - 3x = 45 + 20

2x = 65

x = 65/2

x = 32.5

Hence,

The required number is 32.5
