11. If x is a positive integer such that {3x + 5}/{7}​ is an integer, what is the smallest possible value of x?
    • (a) 1
    • (b) 2
    • (c) 3
    • (d) 4

    Ans: (d) 4

    Solution: Let frac{3x + 5}/{7} = k, where k is an integer. Thus, $3x+5=7k$. Rearranging, 3x=7k−5. For x to be an integer, 7k−5 must be divisible by 3. Trying successive values of k, the smallest $k$ that satisfies this condition is k=3. Substituting, 3x=21−5, so x=16/3. Trying the next k=4, $3x=28-5=23$, so x=23​. Finally, trying k=5,$3x=35-5=30$, so x=10. Hence, the smallest $x$ is 10.

12. A man spends 40% of his monthly salary on rent, 25% on food, and 15% on transportation. If he saves ₹9,000, what is his total monthly salary?
    • (a) ₹30,000
    • (b) ₹36,000
    • (c) ₹40,000
    • (d) ₹45,000

    Ans: (b) ₹36,000

    Solution: Let the monthly salary be S. He spends 40%+25%+15%=80% of his salary, so he saves 100%−80%=20%. If 20%of the salary is ₹9,000, then 100% of the salary is (9,000×100)/20=₹45,000

13. The average of 5 numbers is 15. If two of the numbers are 10 and 20, what is the average of the remaining 3 numbers?
    • (a) 10
    • (b) 12
    • (c) 15
    • (d) 20

    Ans: (a) 10

    Solution: Solution: The sum of the 5 numbers is 5×15=75. The sum of the first two numbers is 10+20=30. Thus, the sum of the remaining 3 numbers is 75−30=45. Therefore, the average of the remaining 3 numbers is 45/3 =15.$5$.

14. A sum of money doubles in 5 years at simple interest. What is the rate of interest per annum?
    • (a) 10%
    • (b) 20%
    • (c) 15%
    • (d) 25%

    Ans: (b) 20%

    Solution: Solution: Let the principal be 𝑃 and the rate of interest be r%. In 5 years, the amount is 2P, and the simple interest is P. Simple interest formula is SI=(P×r×t)/100
    ​Thus, P= (P×r×t)/100​ , so 𝑟=100/5=20%.

15. A train travels from point A to point B in 3 hours at a speed of 60 km/hr. If it travels from B to A at a speed of 90 km/hr, what is the average speed of the train for the entire journey?
    • (a) 72 km/hr
    • (b) 75 km/hr
    • (c) 80 km/hr
    • (d) 85 km/hr

    Ans: (a) 72 km/hr

    Solution: The distance between A and B is 60×3=180 km. Time taken from B to A is 180/90=2 hours. Total distance for the round trip is 180+180=360 km, and total time is 3+2=5 hours. Average speed is 360/5=72 km/hr..

16. The sum of the squares of two consecutive odd numbers is 410. What are the numbers?
    • (a) 9 and 11
    • (b) 11 and 13
    • (c) 13 and 15
    • (d) 15 and 17

    Ans: (b) 11 and 13

    Solution: Let the odd numbers be x and x+2. Then, $=410$. Expanding and solving: $410$, x^2 + 4x + 4 = 410, 2x^2 + 4x = 406, x^2 + 2x = 203=0. Solving $=0$,$(x-11)(x+13)=0$, x=11. Therefore, the numbers are 11 and 13.

17. If a car covers 180 km in 3 hours and another car covers 240 km in 4 hours, what is the ratio of their speeds?
    • (a) 3:4
    • (b) 4:3
    • (c) 2:3
    • (d) 3:2

    Ans: (b) 4:3

    Solution: Speed of the first car is 180/3 =60 km/hr. Speed of the second car is 240/4 =60 km/hr. The ratio of the speeds is 60/60=1:1.

18. A man buys a watch at a discount of 25% on the marked price. If he sells it for ₹9000, what was the marked price?
    • (a) ₹10,000
    • (b) ₹12,000
    • (c) ₹13,500
    • (d) ₹15,000

    Ans: (a) ₹12,000

    Solution: Let the marked price be 𝑀. After a 25% discount, the selling price is 75% of 𝑀 =0.75M=9000, hence M= 9000/0.75 =12000.

19. The sum of three consecutive integers is 69. What are the integers?
    • (a) 22, 23, 24
    • (b) 21, 22, 23
    • (c) 23, 24, 25
    • (d) 20, 21, 22

    Ans: (b) 21, 22, 23

    Solution: Let the integers be x−1, x, and x+1. Then,
    (x−1)+x+(x+1)=69, 3x=69, x=23. Hence, the integers are 22, 23, and 24.

20. A student scores 85, 90, and 80 in three subjects. If the average score needs to be 88 for the fourth subject, what must be the score in the fourth subject?
    • (a) 95
    • (b) 96
    • (c) 97
    • (d) 98

    Ans: (a) 95

    Solution: Let the score in the fourth subject be x.
    The average score is 85+90+80+x =88.
    Solving for 255+x=352,
    x=352−255=97.
