Question 1
1 / -0.33

Most people are afraid of failure and seek only success. Some say failure is the key to success. If a person does not know failure, he would not understand success. Everyone loses at some point in life. In any case, one cannot achieve absolute success in life. What should be an experienced person's advice to people struggling with failures in life?

A
Experience is nothing but learnings from failure.

B
Failure is the stepping stone to success. So, one must seek failure.

C
We cannot succeed without failure and should not always chase success.

D
Failure means inexperience, so we should take initiatives to gain experience, and then succeed.

Solution

The argument is pointing to experience being gained through every opportunity - whether it leads to success or not. Hence, D could be the best advice.

Hence, the correct option is (d).
Question 2
1 / -0.33

What will come next in the following series?

32, 64, 160, 320, 544, 832, ...?

A
32

B
352

C
416

D
1184

Solution

The series starting from 32 32

32+(32 $\times$ 1) = 64

64 +(32 $\times$ 3) = 160

160 + (32 $\times$ 5) = 320

320 + (32 $\times$ 7) = 544

544 + (32 $\times$ 9) = 832

832 + (32 $\times$ 11) = 1184

Hence, the correct option is (d).
Question 3

Hence, the correct option is (b).
Question 4
1 / -0.33

There should be special tax rebates for small scale enterprises as these enterprises create numerous jobs for thousands of people. It is also suggested that company laws should be flexible up to a certain limit for the small scale industries. Which of the following, if true, most severely weakens the argument?

A
Company laws can be easily changed for the sectors that create jobs.

B
Tax rebates and flexibility of laws will encourage people to engage in only small scale enterprises.

C
All the small scale enterprises together generate huge revenues and so tax rebates should be there for them.

D
Most small scale industries, over time, become big enterprises even without any form of rebates or government support.

Solution

If D were true it would mean that with current taxation policies, the small scale industries (most of them) grow into big industries - which means that the current policies and laws help them grow. Hence, the case for special tax rebates and flexibility for small scale industries is weakened. Other statements do not weaken the main argument.

Hence, the correct option is (d).

Which number can replace the question mark in the figure below?

A
10

B
13

C
24

D
28

The top number in each pyramid is irrelevant - otherwise, it is very simple to figure out that it is the multiplication of the last two base numbers and the addition of the first two base numbers that make up the second layer of numbers.

Hence, the correct option is (b).

32 $\times$ 18+25 $\times$ 16 = 976

Therefore: 24 $\times$ 28+52 $\times$ 9 = 1140

Hence, the correct option is (b).
Question 7
1 / -0.33

In a certain code, 'Chocolates cause tooth decay' is written as 'OL U O C', 'Brushing prevents tooth decay' is written as 'SH VE O C' while 'Rahul has toothache' is written as 'H A H'. How will 'Doctor extracted tooth' be coded?

A
C AC OO

B
CT AC OT

C
C TA O

Therefore, 'Doctor extracted tooth' would be coded as CT A O.
