Question : Directions: Which of the following diagrams represents the relationship between Sister, Mother, and Brother?
Option 1:
Option 2:
Option 3:
Option 4:

Question : A man can build a wall in 70 hours. After 7 hours, he takes a break. What fraction of the wall is yet to be built?
Option 1: 0.9
Option 2: 0.8
Option 3: 0.5
Option 4: 0.75
Correct Answer: 0.9
Solution : The work done of a man in 1 hour $=\frac{1}{70}$ ⇒ The work done of a man in 7 hour $=\frac{7}{70}=\frac{1}{10}$ The fraction of the wall that is yet to be built $=1-\frac{1}{10} = \frac{9}{10}=0.9$ Hence, the correct answer is 0.9.
Question : The pie chart given below shows the number of girls in six schools. The total number of girls in all these six schools is 8000. Number of girls in a particular school is shown as a percentage of total number of girls in all these six schools. What is the difference between the central angle formed by sectors M and Q?
Option 1: 64.3°
Option 2: 82.8°
Option 3: 74.3°
Option 4: 93.5°
Correct Answer: 82.8°
Solution : Given, The total number of girls in all these six schools is 8000 The difference between the central angle formed by sectors M and Q $= \frac{\text{ The difference of percentage of M and Q }}{\text{100}}\times 360°$ $=\frac{37-14}{100}\times 360°=\frac{23}{100}\times 360° = 82.8°$ Hence, the correct
Question : Directions: Read the given statements and conclusions carefully. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which conclusions logically follow/s from the given statements. Statements: I. All directors are actors. II. Some actors are writers. III. No writer is a producer. Conclusions: I. Some directors are writers II. No producer is a director
Option 1: Neither conclusion I nor II follows
Option 2: Only conclusion I follows
Option 3: Both conclusions I and II follow
Option 4: Only conclusion II follows
Correct Answer: Neither conclusion I nor II follows
Solution : According to the given statements, the following Venn diagram can be drawn –
Let's analyse the conclusions – Conclusion I: Some directors are writers – From the above diagram, it can be seen that there is no direct relation between
Question : The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don't find any errors, mark 'No error' as your answer. My elder brother / yesterday had took / my Facebook password.
Option 1: my Facebook password
Option 2: yesterday had took
Option 3: My elder brother
Option 4: No error

Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series. 6, 9, 7, 10, 8, 11, ?
Option 1: 12
Option 2: 9
Option 3: 11
Option 4: 10
Correct Answer: 9
Solution : Given: 6, 9, 7, 10, 8, 11, ?
Every alternate number in the series is a consecutive natural number as shown below – (I) 6, 9, 7, 10, 8, 11, ?→6 + 1 = 7; 7 + 1 = 8; 8
Question : Directions: Which number will replace the question mark (?) in the following series? 28, 30, ?, 188, 754, 3772
Option 1: 120
Option 2: 62
Option 3: 60
Option 4: 122
Correct Answer: 62
Solution : Given: 28, 30, ?, 188, 754, 3772
Multiply the number by consecutive natural number and add 2 to the resultant, to get the required missing number – (28 × 1) + 2 = 28 + 2 = 30 (30 × 2) + 2 = 60
Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No Error".

Question : How many multiples of 7 are there between 100 and 200?
Option 1: 14
Option 2: 15
Option 3: 12
Option 4: 16
Correct Answer: 14
Solution : 100 = 7 × 14 + 2 200 = 7 × 28 + 4 Number of multiples of 7 between 100 and 200 = 28 – 14 = 14 Hence, the correct answer is 14.
Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Option 1: 22
Option 2: 30
Option 3: 32
Option 4: 39
Correct Answer: 32
Solution : Multiply the difference of the number of column one and column two by 4, to get the number of the third column –
In row one: (54 – 40) × 4 = 14 × 4 = 56 In row two: (68 – 57) × 4
