Solving percent equations worksheet - Solution
Question 1 :
Evaluate 24% of 16
Solution :
To evaluate 24% of 16, we have to use the multiplication sign instead of the word "of".
24% = 24/100
24% of 16 = (24/100) x 16
= 384/100
= 3.84
Hence the value of 24% of 16 is 3.84
Question 2 :
What percent of 29 is 3?
Solution :
Let "x" be the required percentage
x% of 29 = 3
(x/100) x 29 = 3
29 x/100 = 3
x = 3 (100)/29
x = 300/29
x = 10.3 %
Hence 10.3% of 29 is 3.
Question 3 :
Evaluate 17 ÷ 49 % ?
Solution :
= 17 ÷ (49/100)
= 17 x (100/49)
= (1700/49)
= 34.69
Hence the answer is 34.69.
Question 4 :
Find 8% of 54
Solution :
8% of 54 = (8/100) x 54
= 432/100
= 4.32
Hence 8% of 54 is 4.32
Question 5 :
What percent of 33.5 is 21?
Solution :
Let "x" be the required percentage
x% of 33.5 = 21
(x/100) x 33.5 = 21
33.5x/100 = 21
33.5x = 21(100)
x = 2100/33.5
x = 62.68
Hence 62.68% of 33.5 is 21.
Question 6 :
What percent of 10 is 9?
Solution :
Let "x" be the required percentage
x% of 10 = 9
(x/100) x 10 = 9
x/10 = 9
x = 9(10)
x = 90
Hence 90% of 10 is 9.
Question 7 :
What is 20% of 80?
Solution :
20% of 80
= (20/100) x 80
= 80(80)/100
= 6400/100
= 64
Hence 20% of 80 is 64.
Question 8 :
What is 20% of 80?
Solution :
20% of 80
= (20/100) x 80
= 20(80)/100
= 1600/100
= 16
Hence 20% of 80 is 16.
