A

Rs. 200.

B

Rs. 210.

C

Rs. 190.

D

Rs. 220.

Soln.
Ans: a

Let the calls be for Rs. x. The total bill is x + 5% of x = \${21x}/20 = 210\$, which gives x = Rs. 200.

### Question 2

Mr. X who spends 62% of his salary is able to save Rs. 342. What is his salary?

A

Rs. 900.

B

Rs. 1000.

C

Rs. 800.

D

Rs. 1100.

Soln.
Ans: a

Let the salary be x. His saving% is 100 - 62 = 38, so 38% of x = 342, which gives x = \$342/38\$ × 100 = Rs. 900.

### Question 3

The sum of two numbers is 1560. One of them is 160% of the other. The smaller number is?

A

600.

B

610.

C

590.

D

620.

Soln.
Ans: a

Let the numbers be x and \${160x}/100\$. The sum is x + \${160x}/100\$ which is same as \${260x}/100 = 1560\$. Solving we get the smaller number x = 600.

### Question 4

The number of online customers increased from 1850 to 3575. What is the percentage increase?

\$93{9/37}\$ %.

B

\$96{31/36}\$ %.

C

\$87{20/39}\$ %.

D

\$91{4/13}\$ %.

Soln.
Ans: a

The increase is 3575 - 1850 = 1725. The percentage increase is \$1725/1850\$ × 100 = \${3450/37}\$, which is same as: \$93{9/37}\$.

### Question 5

If 85 is m% of p, and B is p% of m, then what is B?

A

85.

B

95.

C

75.

D

105.

Soln.
Ans: a

Let 85 = A, so A = \$m/100\$ × p = \$p/100\$ × m. = B, so A and B are same.
