Q2. Working alone, the times taken by Anu, Tanu and Manu to complete any job are in the ratio 5 : 8 : 10. They accept a job which they can finish in 4 days if they all work together for 8 hours per day. However, Anu and Tanu work together for the first 6 days, working 6 hours 40 minutes per day. Then, the number of hours that Manu will take to complete the remaining job working alone is
Q3. Regular polygons A and B have number of sides in the ratio 1 : 2 and interior angles in the ratio 3 : 4. Then the number of sides of B equals
Q4.
If aa and bb are non-negative real numbers such that a+2b=6a+2 b=6, then the average of the maximum and minimum possible values of (a+b)(a+b) is
Q5. Manu earns ₹4000 per month and wants to save an average of ₹550 per month in a year. In the first nine months, his monthly expense was ₹3500, and he foresees that, tenth month onward, his monthly expense will increase to ₹3700. In order to meet his yearly savings target, his monthly earnings, in rupees, from the tenth month onward should be
Q6. There are two containers of the same volume, first container half-filled with sugar syrup and the second container half-filled with milk. Half the content of the first container is transferred to the second container, and then the half of this mixture is transferred back to the first container. Next, half the content of the first container is transferred back to the second container. Then the ratio of sugar syrup and milk in the second container is
Q7.
On day one, there are 100 particles in a laboratory experiment. On day nn, where n≥2n \geq 2, one out of every nn particles produces another particle. If the total number of particles in the laboratory experiment increases to 1000 on day mm, then mm equals
Q8.
The average of a non-decreasing sequence of NN numbers a1,a2,…,aNa_1, a_2, \ldots, a_N is 300 . If a1a_1 is replaced by 6a16 a_1, the new average becomes 400 . Then, the number of possible values of a1a_1 is
Q9.
Let rr and cc be real numbers. If rr and −r-r are roots of 5x3+cx2−10x+9=05 x^3+c x^2-10 x+9=0, then cc equals
Q10.
Suppose for all integers xx, there are two functions ff and gg such that f(x)+f(x−1)−1=0f(x)+f(x-1)-1=0 and g(x)=x2g(x)=x^2. If f(x2−x)=5f\left(x^2-x\right)=5, then the value of the sum f(g(5))+g(f(5))f(g(5))+g(f(5)) is
Q11. In an election, there were four candidates and 80% of the registered voters casted their votes. One of the candidates received 30% of the casted votes while the other three candidates received the remaining casted votes in the proportion 1 : 2 : 3. If the winner of the election received 2512 votes more than the candidate with the second highest votes, then the number of registered voters was
Q12. The number of integers greater than 2000 that can be formed with the digits 0, 1, 2, 3, 4, 5, using each digit at most once, is
Q13.

The number of distinct integer values of nn satisfying 4−log⁡2n3−log⁡4n<0\frac{4-\log _2 n}{3-\log _4 n}\lt0, is
Q15. In an examination, there were 75 questions. 3 marks were awarded for each correct answer, 1 mark was deducted for each wrong answer and 1 mark was awarded for each unattempted question. Rayan scored a total of 97 marks in the examination. If the number of unattempted questions was higher than the number of attempted questions, then the maximum number of correct answers that Rayan could have given in the examination is
Q16. Five students, including Amit, appear for an examination in which possible marks are integers between 0 and 50, both inclusive. The average marks for all the students is 38 and exactly three students got more than 32. If no two students got the same marks and Amit got the least marks among the five students, then the difference between the highest and lowest possible marks of Amit is
