Answer : A
Explanation
Step 1:
Part = 72; whole = 80
Step 2:
Percentage = $\frac{72}{80} \times 100 = 90\%$
Step 3:
So, 72 is 90% of 80
Answer : C
Explanation
Step 1:
Let the unknown variable be x
60% of x is 84
So 60% × x = 84; 0.6x = 84
Step 2:
Dividing both sides by 0.6
$\frac{0.6x}{0.6} = x = \frac{84}{0.6} = 140$
Step 3:
So, 60% of 140 is 84
Answer : B
Explanation
Step 1:
Let the unknown variable be x
32% of x is 96
So 32% × x = 96; 0.32x = 96
Step 2:
Dividing both sides by 0.32
$\frac{0.32x}{0.32} = x = \frac{96}{0.32} = 300$
Step 3:
So, 32% of 300 is 96
Answer : D
Explanation
Step 1:
Part = 54; whole = 162
Step 2:
Percentage = $\frac{54}{162} \times 100 = 33.33\%$
Step 3:
So, 54 is 33.33% of 162
Answer : B
Explanation
Step 1:
Part = 48; whole = 192
Step 2:
Percentage = $\frac{48}{192} \times 100 = 25\%$
Step 3:
So, 48 is 25% of 192
Answer : C
Explanation
Step 1:
Let the unknown variable be x
25% of x is 118
So 25% × x = 118; 0.25x = 118
Step 2:
Dividing both sides by 0.25
$\frac{0.25x}{0.25} = x = \frac{118}{0.25} = 472$
Step 3:
So, 25% of 472 is 118
Answer : D
Explanation
Step 1:
Let the unknown variable be x
38% of x is 57
So 38% × x = 57; 0.38x = 57
Step 2:
Dividing both sides by 0.38
$\frac{0.38x}{0.38} = x = \frac{57}{0.38} = 150$
Step 3:
So, 38% of 150 is 57
Answer : A
Explanation
Step 1:
Part = 21; whole = 70
Step 2:
Percentage = $\frac{21}{70} \times 100 = 30\%$
Step 3:
So, 21 is 30% of 70
Answer : C
Explanation
Step 1:
Let the unknown variable be x
60% of x is 126
So 60% × x = 126; 0.6x = 126
Step 2:
Dividing both sides by 0.6
$\frac{0.6x}{0.6} = x = \frac{126}{0.6} = 210$
Step 3:
So, 60% of 210 is 126
Answer : D
Explanation
Step 1:
Part = 48; whole = 200
Step 2:
Percentage = $\frac{48}{200} \times 100 = 24\%$
Step 3:
So, 48 is 24% of 200
