1. Choose the word that is most similar in meaning to “Diligent”.

Expla­na­tion: Dili­gent means hard­work­ing, care­ful and per­sis­tent in com­plet­ing a task. 

2. Choose the word that is opposite in meaning to “Expand”.

Expla­na­tion: Con­tract means to become small­er or reduce in size, mak­ing it the antonym of expand. 

3. Fill in the blank: The manager asked the employees to submit ___ reports before Friday.

Expla­na­tion: “Their” is the pos­ses­sive form and cor­rect­ly indi­cates that the reports belong to the employees. 

4. Identify the correctly spelt word.

Expla­na­tion: The cor­rect spelling is “Accom­mo­da­tion”.

5. Choose the correct improvement: “Neither of the two candidates have submitted the form.”

Expla­na­tion: “Nei­ther” is treat­ed as sin­gu­lar in this con­struc­tion, so “has sub­mit­ted” is correct. 

6. Find the next number in the series: 4, 9, 16, 25, 36, ?

Expla­na­tion: The num­bers are con­sec­u­tive squares: 2², 3², 4², 5², 6². There­fore, the next num­ber is 7² = 49. 

7. If in a certain code, MARKET is written as NBSLFU, how will BANK be written?

Expla­na­tion: Each let­ter is shift­ed one posi­tion for­ward: B→C, A→B, N→O, K→L. There­fore, BANK becomes CBOL. 

8. Ravi is facing north. He turns right, walks 10 metres, turns left and walks 5 metres. In which direction is he facing now?

Expla­na­tion: From north, a right turn makes Ravi face east. A left turn from east brings him back to north. 

9. In a row of 30 students, Riya is 12th from the left. What is her position from the right?

Expla­na­tion: Posi­tion from right = Total stu­dents − Posi­tion from left + 1 = 30 − 12 + 1 = 19. 

10. If P is the brother of Q, Q is the sister of R, and R is the father of S, how is P related to S?

Expla­na­tion: P is the broth­er of Q, while Q is the sis­ter of R. Thus P and R are sib­lings. Since R is S’s father, P is S’s uncle. 

11. Find the missing number: 7, 14, 28, 56, ?

Expla­na­tion: Each num­ber is mul­ti­plied by 2. There­fore, 56 × 2 = 112. 

12. A number is increased by 20% and becomes 360. What was the original number?

Expla­na­tion: Let the orig­i­nal num­ber be x. 120% of x = 360, so x = 360 × 100/120 = 300. 

13. The ratio of two numbers is 3 : 5 and their sum is 64. What is the larger number?

Expla­na­tion: Total parts = 3 + 5 = 8. One part = 64/8 = 8. Larg­er num­ber = 5 × 8 = 40. 

14. A shopkeeper buys an article for ₹1,200 and sells it for ₹1,380. What is the profit percentage?

Expla­na­tion: Prof­it = ₹1,380 − ₹1,200 = ₹180. Prof­it per­cent­age = 180/1200 × 100 = 15%. 

15. A sum of ₹4,000 is invested at 5% simple interest per annum for 3 years. Find the interest.

Expla­na­tion: SI = P × R × T / 100 = 4000 × 5 × 3 / 100 = ₹600.

16. The average of five numbers is 28. If four of the numbers are 20, 24, 30 and 36, what is the fifth number?

Expla­na­tion: Total = 28 × 5 = 140. Sum of four num­bers = 110. Fifth num­ber = 140 − 110 = 30. 

17. A train covers 240 km in 4 hours. What is its average speed?

Expla­na­tion: Speed = Dis­tance ÷ Time = 240 ÷ 4 = 60 km/h.

18. If 40% of a number is 180, what is the number?

Expla­na­tion: 40% of the num­ber = 180. Num­ber = 180 × 100/40 = 450. 

19. If x + 15 = 42, what is the value of x?

Expla­na­tion: x = 42 − 15 = 27. 

20. A can complete a work in 12 days and B can complete the same work in 18 days. In how many days can they complete it together?

Expla­na­tion: A’s one-day work = 1/12 and B’s = 1/18. Togeth­er = 1/12 + 1/18 = 5/36. There­fore, time = 36/5 = 7.2 days.
