**Question 1: **Read the following information and answer the question based on it.

A baby has eight stuffed animals and has placed them into groups of two or three. He has separated the monkey, the llama and the dog into different piles. The first pile includes a lion and a mouse. The elephant and the fish are in the same pile. The eighth animal is a turtle.

Based only on the information above, which of the following must be true?

a) The fish and the Illama are in the same pile.

b) The elephant and the turtle are in the same pile.

c) Three animals may be there in the first pile.

d) Exactly two animals are there in the second pile.

**1) Answer (C)**

**Solution:**

The first pile has a lion and mouse. As the monkey, the ilama and the dog are in different piles so one among them should be in the first peie.

The elephant and fish are in the same pile and one among monkey, ilama and dog will be in that pile but we cannot say if they will be in 2nd pile or 3rd pile. So there will 2 piles of 3 animals of which one is the first pile.

**Question 2: **In a certain language, “ba tu qui zu” implies “zomato provides food delivery”. In the same language “ra ni ma tu” implies “i love good food”; “ba te ma so”implies “love the delivery fresh”; and “so zu tu qui ba” implies “zomato delivery provides fresh food”.

What would be the code of “love the fresh” in this code language:

a) qu ra ni

b) te so ma

c) zu so ba

d) tu te qui

**2) Answer (B)**

**Solution:**

It is given,

ba tu qui zu – zomato provides food delivery …… (1)

ra ni ma tu – i love good food ….. (2)

ba te ma so – love the delivery fresh …… (3)

so zu tu qui ba – zomato delivery provides fresh food …… (4)

In (1), (3) and (4), code ba and word delivery is common. Therefore, code word for delivery is ‘ba’.

We need to find the code for ‘love the fresh’. Removing delivery from (3), we will get the required answer.

Therefore, code of ‘love the fresh’ includes ‘te ma so’. Only option satisfying is option B.

The answer is option B.

**Question 3: **A word arrangement, when rearranged by given input follow a particular rule/logic in each step.Following is an example of input and rearrangement. Study that rule/logic and apply on given problem.

INPUT: man’s mood varies with time and environment

Steps/Results:

I. Varies with man’s mood environment and time

II. And time environment mood man’s varies with

III. Environment time and varies with mood man’s

IV. And varies environment time man’s mood with

If Step IV reads, ‘everyone was aware about their beautiful friendship’, what will be the three middle wordsof Step II?

a) their beautiful aware

b) aware beautiful their

c) everyone were friendship

d) aware were beautiful

**3) Answer (B)**

**Solution:**

Since the question is only considering the 4th and 2nd lines,

Let us consider the third line of the illustration and arrange the 4th and 2nd lines accordingly.

III. Environment time and varies with mood man’s

Let Environment – 1, time – 2, and – 3, varies – 4, with – 5, mood – 6, and man’s – 7.

Now, the coded version of III will be 1234567.

From the illustration, the code IV will be 3412765 and II will be 3216745.

Now after applying a similar code pattern in Step IV of the asked question, step II will be

Everyone about * aware beautiful their* was friendship.

Thus, the correct answer is B.

**Question 4: **Complete the following sequence:

5, 72, 412, 2658, __________?

a) 12772

b) 21264

c) 21512

d) 18876

**4) Answer (C)**

**Solution:**

The series is in the form of $2na_n+62\left(n-1\right)\ ,\ n>1$, where $a_1=5$

For n = 2, $a_2=5\times\ 2+62\times\ 1\ =\ 72$

For n = 3, $a_3=72\times\ 4+62\times\ 2\ =\ 412$

For n = 4, $a_4=412\times\ 6+62\times\ 3=\ 2658$

For n = 5, $a_5=2658\times\ 8+62\times\ 4\ =\ 21512$

Thus the correct option is C.

**Question 5: **In the galaxy “Andromeda”, a planet named “Exo” has a city called “Azith”. The city has analphabet system that consists of 48 letters and an octo-decimal number system (base -18). Theregistration number on the number plate of a vehicle in the city has two parts. The first part is the alphabetpart that consists of three letters and the second part is the number part that consists of 3 digits. The cityadministration issues all kinds of registration numbers with following restrictions:

a. The letters in the alphabet part are in ascending order and all letters must be distinct.

b. In the number part, the first digit is three more than the third digit.

Find the number of possible registration numbers available in the Azith city.

a) 3353270

b) 2557830

c) 5339840

d) 4669920

**5) Answer (D)**

**Solution:**

There are 48 alphabets out of which we need 3

So, no. of ways of selecting 3 alphabets from 48 alphabets is $^{48}C_3$

Since we need to arrange these alphabets in ascending order so there is only one possible way for every three alphabets.

The first digit is 3 more than the third digit.

For a particular first digit there will be a particular third digit but the 2nd digit can be any of the numbers

So, no. of ways of selecting first digit= 15

No. of ways of selecting 2nd digit = 18

Therefore, total no. of ways = $^{48}C_3\times\ 15\times\ 18$ = 4669920

**Question 6: **Based on the information that follows, which of the given options is ** MOSTDEFINITELY TRUE**?

a) The box is big.

b) The can is green.

c) The box does not have toys in it.

d) The can has toys in it.

**6) Answer (D)**

**Solution:**

It is mentioned that there are two containers in a room. One is a box and one is a can.

Can is big. Box is small and green. This implies can is purple and have toys in it.

We do not know what is there in green box.

Therefore, answer is option D.

**Question 7: **Ranbir’s office has two doors facing each other. The front door faces east. He comesout of his office back door and walks 100 metres, turns right and walks 50 metresfurther. The direction he is now from his office is ______________.

a) North-east

b) South-west

c) South-east

d) North-west

**7) Answer (D)**

**Solution:**

The front door is facing east which means that the back door should be facing west.

Ranbir comes out of his from the back door which means he travels in the west direction for 100m and then turns right which means he is now travelling north. So finally Ranbir is in northwest direction from his office.

**Question 8: **The leap day falls on the same day of the week after a gap of at least ______________.

a) 28 years

b) 7 years

c) 5 years

d) 11 years

**8) Answer (A)**

**Solution:**

364 days makes 52 weeks so we will take the remainder days in a year and add them.

For a period of 4 years the no. of days which we get = 2+1+1+1 =5

We have taken a period 4 years as a leap year occurs in every 4 years

Now, we have to make 5 days a multiple of 7 for which we have to multiply it with 7.

So, total years will be 4*7 = 28 years

d) 4

**10) Answer (A)**

**Solution:**

In total, Abeer took part in 8 transactions.

0. Abeer had 14 novels.

1. Gave 3 and received 2 novels. Thus, Abeer had 14 – 3 + 2 = 13 novels.

2. Donated 7 and bought 4 novels. Thus, he had 13 – 7 + 4 = 10 novels.

3. Gives 4 to Joy and takes 5. Thus, he had 10 – 4 + 5 = 11 novels.

4. Gets 3 from Joy. Thus, he had 11 + 3 = 14 novels.

5. Gives 3 to Sanjay and gets 1 novel and 1 magazine. Thus, he had 14 – 3 + 1 = 12 novels and 1 magazine.

6. Gives the magazine to Rahul in exchange for a textbook. Thus, he had 12 novels and 1 textbook.

7. Gives the textbook to Joy and takes a novel. Thus, he had 12 + 1 = 13 novels.

8. Gives Rahul a novel and gets a magazine. Thus, he had 13 – 1 = 12 novels and 1 magazine.

Thus, Abeer does not have any textbooks.

Hence, the answer is option A.

**Solution:**

It is given, product of their ages is 36.

Possible combinations are:

1*1*36 – sum = 38

1*2*18- sum = 21

1*3*12 – sum = 16

1*4*9 – sum = 14

1*6*6 -sum = 13

2*2*9 – sum = 13

2*3*6 – sum = 11

3*3*4 – sum = 10

The census takers comes back and ask for more information implies that the sum is 13. There are two possibilities for only sum 13, as there are two possibilities census taker comes back and asks for other clue.
