Answer: $1100 will represent the amount after 2 years at the rate of 5%.
Step-by-step explanation:
Since we have given that
Principal amount = $1000
Rate of interest = 5%
Time period = 2 years
As we know the formula for "Simple Interest ":

And we know that

So, $1100 will represent the amount after 2 years at the rate of 5%.
Given :
Every square meter of ceiling requires 10.75 tiles.
To Find :
Number of tiles required at :
Ceiling area Number of tiles
1
10
100
Solution :
For, 1 :
Number of tiles required, n = 10.75 tiles.
For, 10 :
Number of tiles required, n = 10.75 × 10 = 107.5 tiles.
For, 100 :
Number of tiles required, n = 10.75 × 100 = 1075 tiles.
Hence, this is the required solution.
