A. 15400

B. 14300

C. 13200**D. 12800**

**Explanation:**

Let the monthly salary of Aamir be Rs. x.

68% of x = 27200

=> x = (27200 * 100)/68 = 40000

His savings = 32/100 * 40000 = 12800.

**582. If two positive numbers are in the ratio 1/8 : 1/5, then by what percent is the second number more than the first?**

A. 40%

B. 33 1/3%**C. 60%**

D. 66 2/3%

E. None of these

**Explanation:**

Given ratio = 1/8 : 1/5 = 5 : 8

Let first number be 5x and the second number be 8x.

The second number is more than first number by 3x.

Required percentage = 3x/5x * 100 = 60%.

**583. If the price of an article went up by 20%, then by what percent should it be brought down to bring it back to its original price?****A. 16 2/3%**

B. 20%

C. 22 1/3%

D. 15%

E. None of these

**Explanation:**

Let the price of the article be Rs. 100.

20% of 100 = 20.

New price = 100 + 20 = Rs. 120

Required percentage = (120 – 100)/120 * 100

= 20/120 * 100 = 50/3 = 16 2/3%.

**584. If P gets 25% more than Q, then by what percent does Q get less than P**

A. 33 1/3%

B. 30%**C. 20%**

**Explanation:**

Let Q get 1 unit.

25% of 1 unit = 1/4 = 0.25

P gets (1 + 0.25) i.e., 1.25 units.

Difference = (1.25 – 1) = 0.25

Required percentage = 0.25/1.25 * 100 = 1/5 * 100 = 20%

D. 6/7**E. None of these**

**Explanation:**

Let the fraction be x/y.

When the numerator decreased by 25% and the denominator decreased by 20%.

(x * 3/4)/(y * 4/5) = 3/4 => x/y = 3/4 * (4/5)/(3/4) = 4/5

**587. Bilal spends 45% of his monthly income on household items, 25% of his monthly income on buying cloths, 7.5% of his monthly income on medicines and saves the remaining amount which is Rs. 9000. Find his monthly income.****A. Rs. 40000**

Let the number be a

Given, 15/100 * 30/100 * 50/100 * a = 90

=> 3/20 * 3/10 * 1/2 * a = 90

=> a = 10 * 20 * 10 * 2 = 4000.

B. 3050

C. 4400

D. 4500

E. None of these

**Explanation**

Let the number be a

Given, 15/100 * 30/100 * 50/100 * a = 90

=> 3/20 * 3/10 * 1/2 * a = 90

=> a = 10 * 20 * 10 * 2 = 4000.

**589. If A got 80 marks and B got 60 marks, then what percent of A’s mark is B’s mark?**

A. 60%

B. 80%

C. 65%**D. 75%**

E. None of these

**Explanation:**

A’s marks = 80 ; B’s marks = 60.

Let x% of A = B => x/100 * 80 = 60

=> x = (60 * 100)/80 = 75

B’s marks is 75% of A’s marks

**590. 3/20 is what percent of 12/25?**

A. 42.75%**B. 31.25%**

C. 35.5%

D. 40.5%

E. None of these

**Explanation:**

Let the required percentage be x%.

3/20 = x% of 12/25 => 3/20 = x/100 * 12/25

=> x = 31.25%.
