Answer:
- 4 is the number that she thought.
Given :
- Anu thinks of a number and subtract 5/2 from it.
- She multiples the result by 8. the result now obtained is 3 times the same number.
To find :
- She thought of what is the number = ?
Step-by-step explanation:
Let the number she thought be x
Then, she subtracted 5/2 from x = 5/2-x.
And, she multiples the result by 8 = (5/2-x) × 8.
According to the question :
(x/1 - 5/2) 8 = 3x
(2x-5/2)8/1=3x
16x-40/2=3x
16x-40=6x
16x-6x=40
10x=40
x=40/10
x=4
Thus, 4 is the number that she thought.
