Answer:
B
Step-by-step explanation:
Formula is
Interest=loan ×interest rate×time
Solve for the first choice
I=10,000×0.05×5=2500
Solve for the second choice
I=10,000×0.06×7=4200
The difference in the amount of interest
4,200−2,500=1700
<h2>
The required value of x is equal to 2.</h2>
Step-by-step explanation:
We have,

To find, the value of x in the given equation = ?
∴ 
By crossmultiplication, we get
3(3x) = x + 16
⇒ 9x = x + 16
⇒ 9x - x = 16
⇒ 8x = 16
⇒ x = 
⇒ x = 2
∴ The value of x = 2
Thus, the required value of x is equal to 2.
