After successfully completing the CAT 2016 sprint series and the SNAP 2016 sprint series, we are back with the XAT 2017 sprint preparation series – Quant 9 to boost your prep. This series will consist of 10 sets of questions from past year XAT papers, leading to XAT 2017 and covered almost all the question types that you needed to know come the 8th of January.

# XAT 2017 sprint preparation series – Quant 9

1. In a square PQRS, A and B are two points on PS and SR such that PA = 2AS, and RB = 2BS. If PQ = 6, the area of the triangle ABQ is

A. 6
B. 8
C. 10
D. 12
E. 14

2. How many whole numbers between 100 and 800 contain the digit 2?

A. 200
B. 214
C. 220
D. 240
E. 248

3. p, q and r are three non-negative integers such that p + q + r = 10. The maximum value of pq + qr + pr + pqr is

A. ≥ 40 and < 50
B. ≥ 50 and < 60
C. ≥ 60 and < 70
D. ≥ 70 and < 80
E. ≥ 80 and < 90

4. A number is interesting if on adding the sum of the digits of the number and the product of the  digits  of  the  number, the result  is  equal  to  the  number.  What fraction of numbers between 10 and 100 (both 10 and 100 included) is interesting?

A. 0.1
B. 0.11
C. 0.16
D. 0.22
E. None of the above

5. Arun has to go to the country of Ten to work on a series of task for which he must get a permit from the Government of Ten. Once the permit  is  issued,  Arun  can enter the country within ten days of the date of Issuance of the permit. Once Arun enters Ten, he can stay for a maximum of ten days. Each of the tasks has a priority, and takes a certain  number of days to complete. Arun cannot work on more than one task at a time.

The  following  table  gives  the  details  of  the  priority  and  the  number  of  days required for each task.

 Task Priority Number of Days Required T1 1 3 T2 2 5 T3 5 3 T4 3 4 T5 4 2

Arun’s first priority is to complete as many tasks as possible, and then try to complete the higher priority tasks. His last priority is to go back as soon as possible. The tasks that Arun should try to complete are:

A. T1 and T2
B. T1, T2 and T5
C. T1, T4 and T5
D. T1, T2 and T4
E. T1, T3 and T4

6. However, Arun’s manager has told him to do some background research on the tasks  before  leaving  for  Ten.  At  the same  time,  there  is  no  guarantee  that Government of Ten will give the permit to  Arun. Background  research  involves substantial costs, and therefore Arun has decided that he will  not  start  his background research without getting the permit.

The following table gives the details of the priority, the number of days required for each task and the number of days required for background research on each task.

 Task Priority Number of Days Required No. of Days required for background research T1 1 3 3 T2 2 5 5 T3 5 3 2 T4 3 4 2 T5 4 2 3

Arun’s first priority is to complete as many tasks as possible, and then try to complete the higher priority tasks. His last priority is to go back as soon  as possible within ten days.

A. T1, T2 and T3
B. T1, T2 and T5
C. T1, T2 and T4
D. T1, T3 and T4
E. T1, T4 and T5

7.The radius of a circle with centre O is √50 cm. A and C are two points on the circle, and B is a point inside the circle. The length of AB is 6 cm, and the length of BC is 2 cm. The angle ABC is a right angle. Find the square of the distance OB

A. 26
B. 25
C. 24
D. 23
E. 22

8. Six playing cards are lying face down on a table, two of them are kings. Two cards are drawn at random. Let a denote the probability that at least one of the cards drawn is  a king, and b denote the probability of not drawing a king. The ratio a/b is:

A. ≥ 0.25 and ≤ 0.5
B. ≥ 0.5 and ≤ 0.75
C. ≥ 0.75 and ≤ 1.0
D. ≥ 1.0 and ≤ 1.25
E. ≥ 1.25

9.Consider the expression: (xxx)b = x3 , where b is the base, and x is any digit of base b. Find the value of b.

A. 5
B. 6
C. 7
D. 8
E.None of the above

10.Consider a function f(x) = x4 + x3 + x2  + x + 1, where x is a positive integer greater than 1. What will be the remainder if f(x5) is divided by f(x)?

A. 1
B. 2
C. 5
D. a monomial in x
E. a polynomial in x

Answers –

1. C. Simply take the fractions as 2x and x on both the sides and find the area of the three right angled triangles. The length of the side will be 3x = 6 and so, the area 5x^2 / 2 will be 10.
2. B. 114+100 = 214.
3. C. Put p = q = r = 10/3. So, we get 100/3+1000/27 = 33.33+27 = 60.xx.
4. A. ab + a + b = 10a + b

9a = ab, b = 9. So, there will be 9 such numbers. 9/91 will be approximately 0.1.
5. B.
6. E.
7. A.
8. E. b = 4c2/6c2 = 4/15 and a = 11/15. So, a/b = 11/4.
9. E. xb^2 + bx + x = x^3

(b^3 – 1)/(b – 1) = x^2. None match.

10. C. Simple division should help here.
