About Exam:

UPSEE is a state level entrance examination for various disciplines. Many prestigious government and private college is associated with this university. UPSEE engineering entrance exam paper is easier than JEE Main and Advanced. It provides good opportunity for those who cannot make to IITs or NITs.

Few random questions from the sample paper are given below:

Q.    If a1.a2 a3,... are terms of AP such that a1 + a5 + a10 + a15 + a20 + a24 = 225, then the sum of first 24 terms is

(a) 9 × 102                                 (b) 9 × 103

(c) 10 × 92                                 (d) 10 × 93

Correct Option: (a)

Sol.     

We know that,

al + a24 = a5 + a20 = a10 + a15        ...(i)

Given,

a1 + a5 + a10 + a15 + a20 + a24 = 225

From equation (i)

3(a1 + a24) = 225

 a1 + a24 = 75

Sum of first n terms of an AP is given as:

       = 12 (75)

       = 900

       = 9 × l02

Q.    The probabilities that Mr. A and Mr. B will die within a year are 1/2 and 1/3 respectively, then the probability that only one of them will be alive at the end of the year, is

(a)    5/6

(b)   1/2

(c)    2/3

(d)   None of the above

Correct Option: (b)

Sol.     

Given,

Probability that Mr. A will die within a year P(A) = 1/2

Q.    The number of solutions of the system ofequations 2x + y -z = 7, x -3y + 2z = 1 and x + 4y -3z = 5 is

(a) 0                                          (b) 1

(c) 2                                          (d) 3

 

Correct Option: (a)

Sol.     

Given,

2x + y -z = 7                                                                                                               ...(i)

x -3y + 2z = l                                                                                                              ...(ii)

and x + 4y -3z = 5                                                                                                      ...(iii)

Multiplying (i) by 2 and then adding (i) and (ii), we get

5x -y = 15                                                                                                                   ...(iv)

Multiplying (i) by 3 and then subtracting (iii) from (i), we get

5x -y = 16                                                                                                                   ...(v)

Eqs. (iv) and (v) shows that they are parallel and so solution does not exist.

Q.     In a right angle ΔABC, angle A = 90° and sides a, b, c are respectively 10 cm, 8 cm and 6c.m.If a force F has moments 0, 64 and 36 N-cm respectively about vertices A, B and C, then magnitude of  F is

(a)   9

(b)   4

(c)   10

(d)   8

 

Correct Option: (c)

Sol.     

Since, moment of F about A is 0, therefore F passes through A. Let the components of F along AB and AC be X and Y respectively, then moment of F about B = 36.

UPSEE 2017

                              6Y = 36

                                Y = 6

Also, moment of F about C = 64

                               8X = 64

                                X = 8

Hence,                    F2 = X2 + Y2

                                 = 64 +36 = 100

                                F = 10

Q.    A train of length 100 m travelling at 20 m/s overtakes another train of length 200 m travelling at 10 m/s. The time taken by the first train to pass the second train is

(a) 30 s                                      (b) 50 s

(c) 10 s                                      (d) 40 s

Correct Option: (a)

Sol.     

Total distance travelled by the first train to pass the second train = (100 + 200)m = 300m

Since first train overtakes second train that means both trains are travelling in the same direction.

So, the relative velocity of the first train = (20 - 10) m/s = 10 m/s

So the time taken by the first train to pass the second train = 300/10 = 30 sec
