Question 1

A bag contains 1380 red, 1740 green and 2880 blue marbles. What percentage of the total is the most visible color in the bag?

 A

48 %.

 B

58 %.

 C

38 %.

 D

68 %.

Soln.
Ans: a

By inspection, blue is the most visible color. The percentage of blue is $2880/{1380 + 1740 + 2880}$ × 100 = 48%.


Question 2

Price of sugar is increased by 60%. By what percentage should consumption be reduced so that the expenditure remains same?

 A

$37{1/2}$ %.

 B

$38{1/2}$ %.

 C

$36{1/2}$ %.

 D

$20{1/4}$ %.

Soln.
Ans: a

Let price be Rs. 100/kg and the consumption be 1 kg. The current expenditure is 100 × 1 = Rs. 100. The new price of sugar is 100 + 60 = Rs. 160/kg. Let the new consumption be c kg. Now, if expenditure is to be same we should have 100 = 160 × c, which gives c = 100/160, so the decrease is 1 - $100/160$ = ${160 - 100}/160$ × 100% = ${75/2}$, which is same as: $37{1/2}$%.


Question 3

Two numbers are, respectively, 5% and 35% less than a third number. What percent is the second of the first?

 A

$68{8/19}$ %.

 B

$73{5/18}$ %.

 C

61 %.

 D

$64{13/21}$ %.

Soln.
Ans: a

If the third number is 100, first number is (100 - 5) = 95, and the second number is (100 - 35) = 65. The required ratio is $65/95$ × 100 = ${1300/19}$, which is same as: $68{8/19}$%.


Question 4

The sum of two numbers is 1712. One of them is 114% of the other. The smaller number is?

 A

800.

 B

810.

 C

790.

 D

820.

Soln.
Ans: a

Let the numbers be x and ${114x}/100$. The sum is x + ${114x}/100$ which is same as ${214x}/100 = 1712$. Solving we get the smaller number x = 800.


Question 5

Mr. X who spends 80% of his salary is able to save Rs. 40. What is his salary?

 A

Rs. 200.

 B

Rs. 300.

 C

Rs. 500.

 D

Rs. 400.

Soln.
Ans: a

Let the salary be x. His saving% is 100 - 80 = 20, so 20% of x = 40, which gives x = $40/20$ × 100 = Rs. 200.
