c) 2: 1

d) 2: 3

Answers :

1). Answer: c)
(2 + 1) (22 + 1) (24+ 1) (28 + 1)

Using this formula

x2 – 1 => (x+1) (x – 1)

= (22 – 20) (22+22) (24+20) (28+20)
= (24 – 20) (24+20) (28+20)
=(28 – 1) (28+1)
= 216 – 1

2). Answer: c)

801 + 40 = 841

√841 = 29

3). Answer: b)

According the divisibility rule of 11, Difference of Sum of alternative numbers is 0 or 11.

3 + N – 4 = 0

N -1 = 0

N = 1

4). Answer:  c)

A         :           B

Efficient         4x        :           1x

Time               1x        :           4x

3x      ———— 45

x         ———–  15

A = 15 days

B = 60 days

A + B = 1/ 15 + 1/ 60 = 5 / 60 = 1/ 12

A and B can complete the work in 12 days

5). Answer: a)

Let cost price = 100

1st discount of 20 % = 100 – 20 = 80 %

2nd Discount of 20 % = 80 – 16 = 64 %

100 – 64 = 36 %

6). Answer: b)

Total scores by 5 players = 39 * 5 = 195

Total score by 4 players = 55 + 30 + 42 + 21 = 148

Score of 5th player = 195 – 148 = 47

7). Answer: d)

8). Answer: c)

Answer: d)

Initial Speed = 33 kmph

Total Distance = 315 km

Speed of train increase certain amount by every hour is a Arithmetic Progress

AP = 

Here N = 7, AP = 315

315 = 7 / 2[(2(33) + (7 – 1) d]

315 *2/7 = 66 + 6d

90 = 66 + 6d

24 = 6d

D = 4

Speed of train increases every hour by 4 kmph
