Question : A can do a work in 48 days. What part of the total work can be done by A in 18 days?
Option 1: $\frac{5}{6}$
Option 2: $\frac{3}{5}$
Option 3: $\frac{3}{8}$
Option 4: $\frac{4}{9}$
Correct Answer: $\frac{3}{8}$
Solution : A can complete the work in 48 days. ⇒ 1 day work of A = $\frac{1}{48}$ Work done by A in 18 days = $\frac{1}{48}×18$ = $\frac{18}{48} = \frac{3}{8}$ Hence, the correct answer is $\frac{3}{8}$.

Question : What is the difference of the factors of the expression $x^2+\frac{1}{x^2}-6$?
Option 1: 0
Option 2: 1
Option 3: 2
Option 4: 4
Correct Answer: 4
Solution : $x^2+\frac{1}{x^2}-6$ = $x^2+\frac{1}{x^2}-2-4$ = $x^2+\frac{1}{x^2}-2×x^2×\frac{1}{x^2}-(2)^2$ = $(x-\frac{1}{x}^2)-(2)^2$ = $(x-\frac{1}{x}+2)(x-\frac{1}{x}-2)$ These are the two factors. So, the difference between them is $(x-\frac{1}{x}+2-x+\frac{1}{x}+2)=4$ Hence, the correct answer is 4.
Question : Directions: What will come in place of the question mark (?) in the following equation if + and – are interchanged and × and ÷ are interchanged? 11 ÷ 4 + 8 × 2 – 1 = ?
Option 1: 41
Option 2: 40
Option 3: 39
Option 4: 43
Correct Answer: 41
Solution : Given: 11 ÷ 4 + 8 × 2 – 1 = ?
After interchanging + with – and × with ÷, the equation becomes – = 11 × 4 – 8 ÷ 2 + 1 = 11 × 4 – 4 + 1 = 44
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 error, mark 'No Error' as your answer.

Option 1: No Error
Option 2: knock so louder
Option 3: in the morning
Option 4: Can you not

Question : The perimeter of two similar triangles ABC and PQR are 36 cm and 24 cm respectively. If PQ = 10 cm. then the length of AB is:
Option 1: 18 cm
Option 2: 12 cm
Option 3: 15 cm
Option 4: 30 cm
Correct Answer: 15 cm
Solution : Since the ratio of the corresponding sides of similar triangles is the same as the ratio of their perimeters. $\triangle{ABC} \sim\triangle{PQR}$ $\Rightarrow \mathrm{\frac{AB}{PQ} = \frac{BC}{QR} = \frac{AC}{PR} = \frac{36}{24}}\\$ $\Rightarrow\mathrm{\frac{AB}{PQ} = \frac{36\;\mathrm{cm}}{24\;\mathrm{cm}}}\\$ $\Rightarrow \mathrm{\frac{AB}{10\;\mathrm{cm}} = \frac{36\;\mathrm{cm}}{24\;\mathrm{cm}}}\\$ $\Rightarrow \mathrm{AB = \frac{36\;\mathrm{cm} \times 10\;\mathrm{cm}}{24\;\mathrm{cm}} = 15\;\mathrm{cm}}$
Question : Directions: Two different positions of the same dice are shown, the six faces of which are numbered from 1 to 6. Select the number that will be on the face opposite to the face showing 3.
Option 1: 4
Option 2: 2
Option 3: 5
Option 4: 1
Solution : Taking dice positions 1 and 2 with 4 as the common face.
Moving clockwise from the common face with 4 –
So, the opposite pairs are –
Therefore, the opposite face of the 3 is 4. Hence, the first option is correct.
