In order to solve this problem, we must solve an equation.
First, we need to define our unknown.
Let's call our number "n".
So, the sum of the number and 6 is the same as saying n+6
Then we need to multiply it by 2 (since it's twice the sum)
2(n+6)
This whole thing is equal to three times of the difference of the number and 8
n-8 is equal to the difference between the number and 8, then we need to multiply it by three.
3(n-8)
now, we set both sides equal and solve
The number is 36
Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
= %
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
= %
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,
Therefore, Option B and F is correct only.
