Question

Amina thinks of a number and subtracts
5/ 2
from it. She multiplies the result by 8. The
result now obtained is 3 times the same number she thought of. What is the number

Answer 1

Answer:

the number is 4

Step-by-step explanation:

let the number be X

x-5/2 = (2x-5)/2

(2x-5)*4=3x

8x-20 = 3x

8x-3x = 20

5x= 20

x= 4

Answer 2

Answer:

Let the number next

So according to question we get

8(x-5/2)=3x

8x-40/2=3x

8x-20=3x

8x-3x=20

5x=20

X=20/5=4

Therefore,x=4

So the required no is 4
