Option 1: 8 ÷ 6 × 9 + 7 – 4 = 12
Option 2: 7 × 8 + 4 – 6 ÷ 3 = 37
Option 3: 9 – 4 × 3 + 6 × 7 ÷ 1 = 12
Option 4: 4 × 8 – 9 ÷ 3 + 7 = 57
Correct Answer: 8 ÷ 6 × 9 + 7 – 4 = 12

Question : 63 men can complete a work in 30 days. In how many days 21 men will do the same work?
Option 1: 70 days
Option 2: 85 days
Option 3: 90 days
Option 4: 88 days
Correct Answer: 90 days
Solution : Here $M_1=63,M_2=21,$ and $D_1=30$ We know, $M_1 ×D_1=M_2 ×D_2$ $⇒63 × 30 = 21 ×D_2$ $\therefore D_2=90$ Hence, the correct answer is 90 days.

Option 3: 8 days
Option 4: $\frac{120}{17}$ days
Correct Answer: 8 days
Solution : $N_1$ alone can do 20% of a piece of work in 6 days. = 100% = 30 days $N_2$ alone can do 20% of the same work in 4 days. = 100% = 20 days $N_3$ alone can do 50% of the same work

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".
I want (1) / that you should (2) / perform well. (3) / No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (2)
Solution : The error lies in the second part of the sentence.
The verbs in the present subjunctive do not follow the subject-verb agreement. Instead, they take the base form of the verb (e.g., be, perform, etc.). So, "that you should" should be replaced with "that you"
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold parts at (1), (2), and (3) that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).
Will you tell me who did accompany you to the airport?
(1) when did accompany you
(2) who must be accompanied you
(3) who accompanied you
(4) No Improvement
Correct Answer: (3)
Solution : The correct choice is the third option.
In this sentence, the word order and the use of did accompany are incorrect. When forming an interrogative sentence, we generally use the interrogative pronoun "who" followed by the simple past form of the verb i.e., accompanied.
Question : If $a-b=11$ and $ab=24$, then the value of $(a^2+b^2)$ is:
Option 1: 169
Option 2: 37
Option 3: 73
Option 4: 48
Correct Answer: 169
Solution : Given: $a-b = 11$ and $ab = 24$ Squaring both sides of the equation: $a-b = 11$, we get, $⇒(11)^{2} = a^{2}+b^{2}-2×ab$ Substituting the value of $ab$ in the above equation and get, $⇒121 = a^{2}+b^{2}-48$ $\therefore a^{2}+b^{2} = 169$ Hence, the correct answer is
