Answer
Let the number = x
(x - (5/2)) ×8 = 3x
8x - (8×5/2) = 3x
8x - 20 = 3x
8x - 3x = 20
5x = 20
x = 20/5
x = 4
Let's check,
(4 - 5/2) = 3/2
3/2× 8 = 24/2 = 12
Hope this will help.....

Answer:
Hey mate following is your ans
let no=x
no=x from connd =x-5/2
no=x from connd =x-5/2thf
no=x from connd =x-5/2thf 8(x-5/2)=3{x}
no=x from connd =x-5/2thf 8(x-5/2)=3{x}8x-20/2=3x
no=x from connd =x-5/2thf 8(x-5/2)=3{x}8x-20/2=3x=5x=10
no=x from connd =x-5/2thf 8(x-5/2)=3{x}8x-20/2=3x=5x=10x=2
no=x from connd =x-5/2thf 8(x-5/2)=3{x}8x-20/2=3x=5x=10x=2
