### 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; 0.6*x* = 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; 0.32*x* = 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; 0.25*x* = 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; 0.38*x* = 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; 0.6*x* = 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
