**Percentage Questions Set 1**

**Q.1. **What is 40 % of 280 ?

- 112
- 116
- 115
- 120

**Answer with Explanation:- (1)**

x % of given no n = (x/100) *n

40% of 280 = (40/100) * 280 = 112

**Q.2.** A fruit seller had some apples. He sells 40% apples and still has 420 apples. Originally, he had

- 620
- 750
- 700
- 680

**Answer with Explanation:- (3)**

Suppose originally he had x apples.

Then, (100 - 40)% of x = 420

(60/100) * x = 420

x = 700

**Q.3. **Whose 35% is 280?

- 700
- 750
- 800
- 850

**Answer with Explanation:- (3)**

Let the required value is x.

As per question; 35% of x = 280

(35/100) * x = 280

x = 800

**Q.4.** If 40% of an amount is 250, what will be 60% of that amount?

- 375
- 320
- 300
- 400

**Answer with Explanation:- (1)**

Let the amount be x.

As per question: 40% of x = 250

(40/100) * x = 250

x = 625

Now, 60% of 625 = (60/100) *625 = 375

**Q.5. **If 30 % of 1520 + 40 % of 800 = x % of 5000, find the value of x.

- 14.42%
- 15.52%
- 12.22%
- 18.82%

**Answer with Explanation:- (2)**

(30/100) * 1520 + (40/100) * 800 = (x/100) * 5000

456 + 320 = (x/100) * 5000

x = 77600/5000 = 15.52%

**Q.6. **If 20% of a = b, then b% of 20 is the same as** **

- 4% of a
- 12% of a
- 7% of a
- 6% of a

**Answer with Explanation:- (1)**

20% of a = b i.e. (20/100)* a = b

b% of 20 = (b/100)* 20 = (20/100)* a * (1/100) * 20 = (4/100) * a = 4% of a

**Q.7. **In an examination, 25% candidates failed in English and 35 % students failed in Math.If 15 % candidates failed in both, what is the percentage of candidates who passed in both the subjects?

- 45 %
- 50 %
- 55 %
- 58 %

**Answer with Explanation:- (3)**

100 - (x + y - z)

x = 25%, y = 35 %, z = 15 %

∴ Required percentage of candidates = 100 - (25 + 35 - 15) = 100 - 45 = 55%

**Q.8. ** Passing marks in an examination are 40%. If a candidate gets 65 marks and fails by 15 marks, the maximum marks in the examination are

- 200
- 220
- 180
- 250

**Answer with Explanation:- (1)**

Apply formula m = 100(y + z)/ (x)

y = 65, z = 15, x = 40

m = 100 * (65 + 15) / 40 = 200

**Q.9.** Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A : B

- 1 : 2
- 4 : 3
- 2 : 5
- 1 : 3

**Answer with Explanation:- (2)**

5% of A + 4% of B = (2/3) * (6% of A + 8% of B)

(5/100)* A + (4/100)*B = (2/3) * (6A/100 + 8B/100)

On solving, we get

A/100 = B/75

A : B = 4 : 3

**Q.10. **If the height of Ramesh is less by 20% than Suresh, the height of Suresh will be greater than that of Ramesh by how many percent?

- 25%
- 30%
- 32%
- 28%

**Answer with Explanation:- (1)**

Apply formula (r / (100-r)) * 100 %

r = 20%

Required Percentage = (20 / (100-20)) * 100 %

= (20/80) * 100 = 25%
