Practice the questions so as to familiarize yourself with the pattern of questions to be asked in the exam.

**Directions(1-5):** Find the correct relation between x and y and choose a correct option.

- I. 2x^2+x– 6 = 0

II. 3y^2+y– 8 = 0x=y or relation cannot be established.x>yx>=yy>=xy>xOption A

I. 2x^2+x– 6 = 0

2x^2+4x–3x– 6 = 0

x = -2,1.5

II. 3y^2+y– 8 = 0

3y^2+6y–4y– 8 = 0

y = -2, 1.33

Hence, no relation - I. x^3 – 375 = 3000

II. y^3 + 600 = 769x=y or relation cannot be established.y>xy>=xx>=yx>yOption E

x = 15

y = 13

x > y - I. 225x^2 – 4 = 0

II. √225y + 2 = 0x=y or relation cannot be established.x>=yx>yy>=xy>xOption B

225x^2 – 4 = 0

(15x)^2 – (2)^2 = 0

(15x + 2) (15x – 2) = 0

x = – 2/15, 2/15

15y + 2 = 0

y = – 2/15

x >= y - I. 2x^2 + x – 1 = 0

II. 2y^2 – 3y + 1 = 0x>yx>=yx=y or relation cannot be established.y>xy>=xOption E

2x^2 + x – 1 = 0

2x^2 + 2x – x – 1 = 0

2x (x + 1) – 1 (x + 1) = 0

x = – 1, 1/2

2y^2 – 3y + 1 = 0

2y^2 – 2y – y + 1 = 0

2y (y – 1) – 1 (y – 1) = 0

y = 1, ½

y>=x - I. x^2 + x – 2 = 0

II. y^2 + 5y + 6 = 0x=y or relation cannot be established.y>=xy>xx>yx>=yOption E

x ^2 + 2x – x – 2 = 0

x (x + 2) – 1 (x + 2) = 0

x = 1, – 2

y^2 + 5y + 6 = 0

y^2 + 3y + 2y + 6 = 0

y (y + 3) + 2 (y + 3)

y = – 2, – 3

x>=y - 30 labourers working 7 hours a day can finish a piece of work in 18 days. If the labourers work 6 hours a day, then find the number of labourers required to finish the same piece of work in 30 days.
3021182517Option B

Required number of labourers

= (30*7*18)/(6*30) = 21 - An amount of Rs. 400 becomes Rs. 424 in 3 years at a certain rate of simple interest, If the rate of interest increases by 8%, what amount will Rs. 400 becomes in 2 years?
Rs. 480Rs. 320Rs. 420Rs. 580Rs. 400Option A

SI = 424 – 400 = Rs. 24

R = (24 × 100)/(400 × 3) = 2%

New rate = 2 + 8 = 10%

SI = (400 × 10 × 2)/100 = Rs. 80

Amount = 400 + 80

= Rs. 480 - Average age of A and B, 2 years ago was 26. If age of A 5 years hence is 40 yrs, and B is 5 year younger to C, then find difference between age of A and C?
8 years7 years5 years9 years6 yearsOption D

Average age of A and B 2 year ago = 26

Present Average age = A + B/ 2 = 28

Present age A + B = 56

A’s age after 5 year = 40

Now A’s age = 40 – 5 = 35

B’s age = 56 – 35 = 21

C’s age = 21 + 5 = 26

Required difference = 35 – 26 = 9 years - Ratio of speed of boat in down stream and speed of stream is 9:1, if speed of current is 3 km per hr, then find distance travelled(in km) upstream in 5 hours.
111 km120 km113 km105 km90 kmOption D

speed of current = y = 3

Downstream speed = 9 × 3 = 27 km/h

Speed of boat = x

x + y = 27

x = 24

y= 3

Distance travelled = speed × Time

= (x – y) × 5

= (24 – 3) × 5

= 21 × 5 = 105 km - How many different words can be formed with the letters of the word UNIVERSITY so that all the vowels are together?
6240060480614606844064480Option B

Number of words = (4! * 7!)/2 = 60480
