Question : Directions: In the following number pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the option in which the numbers are related in the same way as the numbers of the following pairs. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 9, 56 17,104
Option 1: 11, 83
Option 2: 8, 51
Option 3: 12, 69
Option 4: 15, 92
Correct Answer: 15, 92
Solution : Given: 9, 56 17,104
Here, multiply the first number by 6 and then add 2 to the resultant to get the second number – ⇒ 9, 56→9 × 6 + 2 = 56 ⇒ 17,104→17 × 6 + 2 = 104

Question : A man retired from his service at the age of 60. He served for $\frac{3}{5}$th years of his retirement age. He joined his job at the age of:
Option 1: 18 years
Option 2: 20 years
Option 3: 24 years
Option 4: 36 years
Correct Answer: 24 years
Solution : Total years, he served = $60 \times \frac{3}{5}$ = 36 years So now we have the total years he has served So, the age at which he had joined for the job = 60 – 36 = 24 years Hence, the correct answer is

Question : Study the given table and answer the question that follows. The table shows the number of copies of a book sold by seven different shops on a particular day.
The cost of each copy of the book is INR 70. What is the total cost of all the copies of the book that were sold on that day from all these seven shops taken together?
Option 1: INR 30,500
Option 2: INR 21,500
Option 3: INR 24,500
Option 4: INR 27,500
Correct Answer: INR 24,500
Solution : The total cost of all the copies of the book of all the shops $=(42+38+61+39+51+59+60)\times 70$ $=350\times 70$ $=24500$ Hence, the correct answer is INR 24,500.
Question : If $26a + 26b = 234$, then what is the average of $a$ and $b$?
Option 1: 9
Option 2: 4.5
Option 3: 5.5
Option 4: 5
Correct Answer: 4.5
Solution : Given: $26a + 26b = 234$ ⇒ $26(a + b) = 234$ ⇒ $a + b = \frac{234}{26}$ ⇒ $a + b = 9$ So, the average $=\frac{a+b}{2} = \frac{9}{2} = 4.5$ Therefore, the average of $a$ and $b$ is 4.5. Hence, the correct answer
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.

Question : If $P:Q=1: 3, Q:R=3:4,$ and $R: S=2:1$, then what is the value of $P:S$?
Option 1: $3:1$
Option 2: $2:1$
Option 3: $1:2$
Option 4: $3:2$
Correct Answer: $1:2$
Solution : $P: Q = 1 : 3, Q: R = 3: 4, R: S = 2 : 1$ So, $P:Q: R=1:3:4$ Now, $R:S=2:1⇒R:S=4:2$ So, $P:Q:R: S=1:3:4:2$ $\therefore P : S = 1 : 2$ Hence, the correct answer is $1 : 2$.
