Answer : C
Explanation
Step 1:
Rewriting 88 = 88.0
Step 2:
To find 10% we move the decimal one place to the left to get 8.8
Step 3:
So, 10% of 88.0 = 8.8
Answer : B
Explanation
Step 1:
Rewriting 60 = 60.0
Step 2:
We find 10%. We move the decimal one place to the left to get 6.0
Step 3:
To find 5% we take its half or divide it by 2.
So, 5% of 60.0 = $\frac{6.0}{2} = 3.0 = 3$
Answer : A
Explanation
Step 1:
25% = $\frac{25}{100} = \frac{1}{4}$
Step 2:
To get 25% of 180 we divide it by 4
25% of 180 = $\frac{180}{4} = 45$
Step 3:
So, 25% of 180 = 45
Answer : D
Explanation
Step 1:
50% = $\frac{50}{100} = \frac{1}{2}$
Step 2:
To get 50% of 240 we divide it by 2
50% of 240 = $\frac{240}{2} = 120$
Step 3:
So, 50% of 240 = 120
Answer : A
Explanation
Step 1:
Rewriting 270 = 270.0
Step 2:
We find 10%. We move the decimal one place to the left to get 27.0
Step 3:
To find 20% we multiply the result by 2.
So, 20% of 270 = 27 × 2 = 54
Answer : D
Explanation
Step 1:
Rewriting 96 = 96.0
Step 2:
To find 10% we move the decimal one place to the left to get 9.6
Step 3:
So, 10% of 96.0 = 9.6
Answer : B
Explanation
Step 1:
Rewriting 320 = 320.0
Step 2:
We find 10%. We move the decimal one place to the left to get 32.0
Step 3:
To find 30% we multiply the result by 3.
So, 30% of 320 = 32 × 3 = 96
Answer : C
Explanation
Step 1:
75% = $\frac{75}{100} = \frac{3}{4}$
Step 2:
To get 75% of 320 we multiply 160 by $\frac{3}{4}$
75% of 160 = $\frac{3}{4} \times 160 = 120$
Step 3:
So, 75% of 160 = 12
Answer : A
Explanation
Step 1:
Rewriting 220 = 220.0
Step 2:
We find 10%. We move the decimal one place to the left to get 22.0
Step 3:
To find 5% we take its half or divide it by 2.
So 5% of 220.0 = $\frac{22.0}{2} = 11.0 = 11$
Step 4:
To find 15% we add the 10% and 5% found
15% of 220 = 10% of 220 + 5% of 220
= 22 + 11 = 33
So, 15% of 220 = 33
Answer : B
Explanation
Step 1:
Rewriting 480 = 480.0
50% = $\frac{50}{100} = \frac{1}{2}$
Step 2:
To get 50% of 480 we divide it by 2
50% of 480 = $\frac{480}{2} = 240$
Step 3:
Now we find 10% of 480. We move the decimal one place to the left to get 48.0
Step 4:
60% of 480 = 50% of 480 + 10% of 480
= 240 + 48 = 288
So, 60% of 480 = 288
