Question : Directions: Read the following pie chart carefully to answer the question. Distribution of sales of Hindi and English newspapers in five localities (A, B, C, D, and E).
English newspaper:
Hindi newspaper: What is the ratio of the average number of sales of English newspapers in localities B and D together to the average sale of Hindi newspapers in all the localities?
Option 1: 25 : 32
Option 2: 40 : 33
Option 3: 33 : 40
Option 4: 43 : 33
Correct Answer: 25 : 32
Solution : The average sales of English newspapers in localities B and D = $\frac{2000+3000}{2}$ = $\frac{5000}{2}$ = 2500 The average sale of Hindi newspapers in all the localities = $\frac{4000+2500+3600+2400+3500}{5}$ = $\frac{16000}{5}$ = 3200 The ratio of the average sales of English newspapers in
Question : A and B together can complete a piece of work in 18 days, B and C in 24 days, and A and C in 36 days. In how many days, will all of them together complete the work?
Option 1: 16 days
Option 2: 15 days
Option 3: 12 days
Option 4: 10 days
Correct Answer: 16 days
Solution : 1 day work of A and B = $\frac{1}{18}$ ---------(1) 1 day work of B and C = $\frac{1}{24}$ ---------(2) 1 day work of A and C = $\frac{1}{36}$ ---------(3) Adding equations (1), (2) and (3), we get: ⇒ 2 × (A + B
Question : The ratio of the volume of the two cones is 2 : 3, and the ratio of the radii of their bases is 1 : 2. The ratio of their heights is:
Option 1: 3 : 8
Option 2: 8 : 3
Option 3: 4 : 3
Option 4: 3 : 4
Correct Answer: 8 : 3
Solution : Let their radii be $x$ and $2x$ and their heights be $h$ and $H$ respectively. According to the question, $\frac{V_1}{V_2}=\frac{\frac{1}{3}\pi r_1^2 h_1}{\frac{1}{3}\pi r_2^2 h_2}$ ⇒ $\frac{V_1}{V_2}=\frac{r_1^2 h_1}{r_2^2 h_2}$ ⇒ $\frac{2}{3}=\frac{x^2 h}{(2x)^2 H}$ ⇒ $\frac{2}{3}=\frac{x^2 h}{4x^2 H}$ ⇒ $\frac{h}{H}=\frac{8}{3}$ Hence, the correct answer is
Question : If $p^{3}-q^{3}=(p-q)[(p+q)^{2}-xpq$, then the value of $x$ is:
Option 1: 1
Option 2: –1
Option 3: 2
Option 4: –2
Correct Answer: 1
Solution : Given: $p^{3}-q^{3}=(p-q)[(p+q)^{2}–xpq]$ ⇒ $p^{3}-q^{3}=(p-q)(p^{2}+q^{2}+2pq–xpq)$ ⇒ $p^{3}-q^{3}=(p-q)(p^{2}+q^{2}+pq(2-x)$ ----(1) We know the formula of $a^{3}-b^{3}=(a-b)(a^{2}+ab+b^{2})$ Comparing this with equation (1), we have: ⇒ $(2-x)=1$ ⇒ $x=1$ Hence, the correct answer is 1.
Question : The enzyme that converts glucose to ethyl alcohol is:
Option 1: Invertase
Option 2: Maltase
Option 3: Zymase
Option 4: Diastase
Correct Answer: Zymase
Solution : The correct option is - Zymase
Zymase is a complex of enzymes found in yeast cells, and it plays a key role in the fermentation process that converts glucose (or other sugars) into ethanol (ethyl alcohol) and carbon dioxide.
Question : Select the most appropriate option to fill in the blank.

Footpath is a path or track that is laid on the side of roads for people to walk on. This helps convey that the peanut stove, which was present on the path where people walk, makes them think
Question : Direction: If Ramya's rank is 22nd out of 46 students, what is her rank from the last?
Option 1: 26
Option 2: 25
Option 3: 32
Option 4: 24
Correct Answer: 25
Solution : Given:
This means that there are 21 students ahead of Ramya.
Then, Ramya's rank from the last is 46 – 21 = 25
Hence, the second option is correct.
Question : Directions: In each of the following, questions, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. M can be represented by 01, 23, etc, and E can be represented by 58, 88 etc. Similarly, you have to identify the set for the word given in each question.

Option 1: 11, 66, 33, 96
Option 2: 11, 67, 32, 97
Option 3: 31, 87, 32, 97
Option 4: 31, 66, 33, 97
Correct Answer: 31, 87, 32, 97
Solution : Given: LANE
Number representations of each letter – L→11, 31 A→66, 87, 99 N→32 E→58, 79, 88, 97
First option: 11, 66, 33, 96; N and E cannot be represented as 33 and 96 respectively. Second option: 11, 67, 32, 97; A
Question : Directions: If A means add, B means divide, C means multiply and D means subtract, then 180 B 36 C 5 A 8 D 32 = ?
Option 1: 0
Option 2: 3
Option 3: 1
Option 4: 2
Solution : Given: 180 B 36 C 5 A 8 D 32 = ?
On replacing the letters with mathematical signs, the equation becomes – = 180 ÷ 36 × 5 + 8 – 32 = 5 × 5 + 8 – 32 = 25 + 8
