Latest Basic Percentage MCQ Objective Questions
Basic Percentage Question 1:
Out of an earning of ₹ 720, Rama spends 65%. How much does she save?
Answer (Detailed Solution Below)
Basic Percentage Question 1 Detailed Solution
Given:
Rama's earning = ₹720
Spending percentage = 65%
Formula used:
Savings = Total Earning - Spending
Spending = Total Earning × Spending percentage
Calculations:
Spending = 720 × (65/100)
⇒ Spending = 720 × 0.65 = ₹468
Savings = 720 - 468
⇒ Savings = ₹252
∴ The correct answer is option (1).
Basic Percentage Question 2:
P and Q are two fixed points 10 cm apart, and R is a point on PQ such that PR = 6 cm. By what percentage is the length of QR decreased when the length of PR is increased by 5%?
Answer (Detailed Solution Below)
Basic Percentage Question 2 Detailed Solution
Given:
P and Q are two fixed points 10 cm apart.
PR = 6 cm.
Formula Used:
\(Percentage decrease in length = \frac{\text{Original Length} - \text{New Length}}{\text{Original Length}} × 100%\)
Calculation:
Original length of QR = PQ - PR
Original length of QR = 10 cm - 6 cm
Original length of QR = 4 cm
Increase in PR by 5%
New length of PR = 6 cm + (5% of 6 cm)
New length of PR = 6 cm + 0.3 cm
New length of PR = 6.3 cm
New length of QR = PQ - PR
New length of QR = 10 cm - 6.3 cm
New length of QR = 3.7 cm
Percentage decrease in length = \(\frac{4 cm - 3.7 cm}{4 cm} × 100%\)
⇒ Percentage decrease in length = \(\frac{0.3 cm}{4 cm} × 100%\)
⇒ Percentage decrease in length = 0.075 × 100%
⇒ Percentage decrease in length = 7.5%
The correct answer is option 2.
Basic Percentage Question 3:
Out of the total toffees, \(\frac{1}{10}\) are wasted. 35% of the rest are given to S and \(\frac{1}{8}\) of the total are given to N. If the toffees with N are 10 more than the wasted toffees, then how many toffees were given to S?
Answer (Detailed Solution Below)
Basic Percentage Question 3 Detailed Solution
Given:
Total wasted toffees = (1/10) × Total toffees
Toffees got by S = 35% of remaining toffees
Toffees got by N = (1/8) of total toffees
Calculation:
Let the total toffees = 200 units
Total wasted toffees = 200 × (1/10) = 20 units
Remaining toffees = (200 - 20) = 180 units
Total toffees S had = 180 × 35% = 63 units
Total toffees N had = (1/8) × 200 = 25 units
According to the question:
⇒ (25 - 20) units = 5 units = 10 toffees
⇒ 1 units = 2 toffees
Total toffees S had = 63 units = 63 × 2 = 126 toffees
∴ The correct answer is 126 toffees.
Basic Percentage Question 4:
Which of the following is the least?
12% of 625
15% of 555
10% of 720
9% of 845
Answer (Detailed Solution Below)
Basic Percentage Question 4 Detailed Solution
Calculation:
12% of 625 = 75
15% of 555 = 83.25
10% of 720 = 72
9% of 845 = 76.05
So, 10% of 720 is the least
∴ The correct answer is option 3
Basic Percentage Question 5:
Out of an earning of Rs. 720, Pankaj spends 65%. How much does he save?
Answer (Detailed Solution Below)
Basic Percentage Question 5 Detailed Solution
Given:
Out of an earning of Rs. 720, Pankaj spends 65%.
Calculation:
Savings of Pankaj = 720 × (100 - 65)%
⇒ 720 × 35%
⇒ 252
∴ He saves Rs. 252.

Basic Percentage Question 11:
P and Q are two fixed points 10 cm apart, and R is a point on PQ such that PR = 6 cm. By what percentage is the length of QR decreased when the length of PR is increased by 5%?
Answer (Detailed Solution Below)
Basic Percentage Question 11 Detailed Solution
Given:
P and Q are two fixed points 10 cm apart.
PR = 6 cm.
Formula Used:
\(Percentage decrease in length = \frac{\text{Original Length} - \text{New Length}}{\text{Original Length}} × 100%\)
Calculation:
Original length of QR = PQ - PR
Original length of QR = 10 cm - 6 cm
Original length of QR = 4 cm
Increase in PR by 5%
New length of PR = 6 cm + (5% of 6 cm)
New length of PR = 6 cm + 0.3 cm
New length of PR = 6.3 cm
New length of QR = PQ - PR
New length of QR = 10 cm - 6.3 cm
New length of QR = 3.7 cm
Percentage decrease in length = \(\frac{4 cm - 3.7 cm}{4 cm} × 100%\)
⇒ Percentage decrease in length = \(\frac{0.3 cm}{4 cm} × 100%\)
⇒ Percentage decrease in length = 0.075 × 100%
⇒ Percentage decrease in length = 7.5%
The correct answer is option 2.

Basic Percentage Question 14:
In an examination every candidate took Physics, Mathematics or both. 65.8% took Physics and 59.2% took Mathematics. The total number of candidates was 2000. How many took both mathematics and Physics?
Answer (Detailed Solution Below)
Basic Percentage Question 14 Detailed Solution
Given:
Percentage of candidates who took Physics = 65.8%
Percentage of candidates who took Mathematics = 59.2%
Total number of candidates = 2000
Formula Used:
Using the principle of inclusion and exclusion:
Number of candidates who took both subjects = (Number of candidates who took Physics) + (Number of candidates who took Mathematics) - (Total number of candidates)
Calculation:
Number of candidates who took Physics = 65.8% of 2000
Number of candidates who took Physics = 2000 × 0.658
Number of candidates who took Physics = 1316
Number of candidates who took Mathematics = 59.2% of 2000
Number of candidates who took Mathematics = 2000 × 0.592
Number of candidates who took Mathematics = 1184
Number of candidates who took both subjects:
Number of candidates who took both subjects = 1316 + 1184 - 2000
⇒ Number of candidates who took both subjects = 2500 - 2000
⇒ Number of candidates who took both subjects = 500
The number of candidates who took both Mathematics and Physics is 500.
