Question 1

1/25 of a boy's score in Maths exceeds 1/28 of his score in English by 16 marks. What is his score in English, if his total score in English and Maths is 612?

 A

112 marks.

 B

114 marks.

 C

110 marks.

 D

116 marks.

Soln.
Ans: a

Let the score in English be E, then his score in math is 612 - E. We have also been given $(612 - E)/25 = E/28 + 16$. Solving for E, we get E = 112.


Question 2

Cost of 1 kg of a metal is Rs. $29{1/2}$. What is the cost of ${58/59}$ kg?

 A

Rs. 29.

 B

Rs. 30.

 C

Rs. 28.

 D

Rs. 31.

Soln.
Ans: a

We have to find $29{1/2}$ × ${58/59}$, which can be written as ${59/2}$ × ${58/59}$, which simplifies to 58/2 = Rs. 29.


Question 3

What is -341 + (-354) - (-393) + 418?

 A

116.

 B

117.

 C

115.

 D

118.

Soln.
Ans: a

We have -341 + (-354) - (-393) + 418 = -341 - 354 + 393 + 418 = -(341 + 354) + (393 + 418) = -695 + 811 = 116.


Question 4

What is 547 × 79?

 A

43213.

 B

43222.

 C

43204.

 D

43231.

Soln.
Ans: a

This is a multiplication by a number whose units place is 9. Proceed like this: 547 × 79 = 547 × (70 + 9) = 547 × (70 + 10 - 1) = (547 × 70) + (547 × 10) - 547 = 38290 + 5470 - 547 = 43213. The other approach could have been 547 × 79 = 547 × (80 - 1), etc.,


Question 5

A candidate attempts 129 questions and gets a score of 131. How many questions did he attempt wrongly, if 4 marks are awarded for a correct answer, and 1 is deducted for a wrong answer?

 A

77.

 B

78.

 C

76.

 D

79.

Soln.
Ans: a

Had he attempted all correctly, he would have got 129 × 4 = 516. But he has lost 516 - 131 = 385 marks due to wrong attempts. Each wrong attempt leads to an overall loss of 5 marks, so the number of wrong attempts is 385/5 = 77.
