4. In an examination, Ram, Mohan and Raj scored 28%, 36% and 53% marks respectively. Out of these three candidates, two passed the exam, and out of these two, one passed with 33 marks more than the pass marks, while Ram failed by 17 marks. Find the pass marks.
A) 192
B) 73
C) 112
D) Can’t be determined
E) None of these
Correct answer: D
Solution:
Let the pass marks be x and the total marks be y.
So, x – 17 = 0.28y … (i) x + 33 = 0.36y … (ii) or, x + 33 = 0.53y … (iii) Again, solving (i) and (ii), x = 192, y = 625 Again, solving (i) and (iii) x = 73, y = 200 Hence we can’t determine the pass marks. Note: Here, Mohan and Raj passed with 33 more marks. The two different candidates give different values of pass marks. In other words, two equations give two different values. Thus, cannot be determined. 5.A solid diamond falls and breaks into three pieces whose weights are in the ratio of 2 : 3 : 4. The value of each piece is directly proportional to the square of their weights. Given that the value of solid diamond is Rs.24300, find the loss due to breakage.

Directions: Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read the questions and both the statements and give answer 6.What is the average of P, 40, 60, 76, S and T?
A) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

7.What is the percentage profit earned by selling a car for Rs.640000?
I. The amount of profit earned by selling the car is Rs.320000.
II. The SP of the car is twice the CP.
A) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
B) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
C) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
D) if the data in both statement I and II together are not sufficient to answer the question.
E) if the data in both statement I and II together are necessary to answer the question.
Correct answer: C
Solution:
From I. CP = 640000 – 320000
= Rs.320000
Hence from I we can find the percentage profit.
From II. SP = 2 × CP
If CP be x then SP will be 2x. So 100% profit will be earned.
8 Is a twodigit number divisible by 16?
I. The sum of the two digits of the number is 10.
II. The product of the two digits of the number is 24.
A) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
B) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
C) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
D) if the data in both statement I and II together are not sufficient to answer the question.
E) if the data in both statement I and II together are necessary to answer the question.
Correct answer: D
Solution:
