Question

Add 2 to me. Then multiply by 5 and subtract 10 and divide now by 4 and i will give you 15! Who am i?

Answer 1

Answer:

12

Step-by-step explanation:

Given Add 2 to me. Then multiply by 5 and subtract 10 and divide now by 4 and i will give you 15! Who am i?

So Let the unknown number be x. Add to it we get x + 2. Again multiply by 5, we get (x + 2) x 5.

We get 5 x + 10. Now subtract 10 to this we get

5 x + 10 – 10. We get 5 x. Divide this by 4

So 5 x/ 4 = 15

5 x = 15 x 4

5 x = 60

x = 60 / 5

x = 12

Answer 2

Answer:

12

Step-by-step explanation:

Let the number = x

1) Add 2 to x.

     x + 2

2) Multiply the result by 5

    (x + 2) x 5

3) Subtract 10 from the result in 2

    [(x + 2) x 5] - 10

4) Divide the result in 3 by 4

    {[(x + 2) x 5] - 10} / 4

5) Given that the result in 4 is equal to 15

     {[(x + 2) x 5] - 10} / 4 = 15

=> [(x + 2) x 5] - 10 = 60

=> 5x + 10 - 10 = 60

=> 5x = 60

=>x = 12

So, the required number is 12.
