Question : The ratio of time taken to complete a work by a man and a woman is 2 : 3. The man and the woman can complete the work together in 24 days. In how many days can the woman complete the work alone?
Option 1: 20 days
Option 2: 40 days
Option 3: 60 days
Option 4: 30 days
Correct Answer: 60 days
Solution : A man and a woman can complete the work together in 24 days. Time = $\frac{\text{Work}}{\text{Efficiency}}$ Time is inversely proportional to efficiency. ⇒ Ratio of time taken = $2 : 3$ $\therefore$ Ratio of efficiencies = $3 : 2$ Total work = $(3 +
Question : A certain number of persons can complete a work in 90 days. If there were 10 persons less, it would have taken 10 days more for the work to be completed. Find the total number of persons in the beginning.
Option 1: 90
Option 2: 110
Option 3: 85
Option 4: 100
Correct Answer: 100
Solution : Given, Time taken by a certain number of persons = 90 days The difference in days if 10 persons less = 10 days Let the number of persons present initially be $x$. Now, the Work done is the same ⇒ $x\times90 = (x-10)\times100$ ⇒ $90x

Question : Sentences of a paragraph are given below. While the first and the last sentences (S1 and S6) are in the correct order, the sentences in between are jumbled up and named P, Q, R, and S. Arrange the sentences in the correct order to form a meaningful and coherent paragraph.
(S1) Newspapers, especially of the popular variety, aim to do two things: to inform and to entertain.
(P) Entertainment may be principally found in the centre pages of the newspaper in some of the feature articles and in some local news stories. (Q) The principal aim of the short news report on the front pages is to inform. (R) Most newspapers are published daily, and the news reporters must make sure that they have up-to-the-minute news. (S) In their news reports, they will aim to create a sense of immediacy, to convey the impression that they have 'rushed' the news to the reader and 'that the information contained in the very latest.'
(S6) Reporters also wish to create a sense of authenticity, that is, that their news is accurate and genuine.
Option 1: Q, S, R, P
Option 2: R, P, S, Q
Option 3: S, R, P, Q
Option 4: P, Q, R, S
Correct Answer: P, Q, R, S
Solution : The correct order is the fourth option, i.e., P, Q, R, S.
Sentence (P) comes first after S1 because it expands on the aspect of entertainment. After that, sentence (Q) is the most appropriate because it introduces the primary purpose
Question : Directions: In a certain language REKHA is written as NOPST, RESHAM is written as NOHSTQ and SHYAM is written as HSLTQ. What will be SHAME written as?
Option 1: SHQTO
Option 2: HSTQO
Option 3: HSTOQ
Option 4: SHQOT
Correct Answer: HSTQO
Solution : Given: REKHA is written as NOPST, RESHAM is written as NOHSTQ and SHYAM is written as HSLTQ.
Each letter of the word is assigned an individual letter code – R→N, E→O, K→P, H→S, A→T Thus, REKHA is written as NOPST. And, RESHAM is written as
Question : A and B can do a work in $26 \frac{2}{3}$ days. B and C together can complete the same work in 48 days, while A and C together can complete the same work in 30 days. How long (in days) will A alone take to complete 60% of the work?
Option 1: 20
Option 2: 32
Option 3: 24
Option 4: 36
Correct Answer: 24
Solution : Use : Work = Efficiency × Time According to the question LCM of $\frac{80}{3}$, 48 and 30 = 720 ⇒ Efficiency of A and B = 720 × $\frac{3}{80}$ = 27 ⇒ Efficiency of B and C = $\frac{720}{48}$ = 15 ⇒ Efficiency of A

Question : A kite is flying at a height of 50 metres. If the length of the string is 100 metres, then the inclination of the string to the horizontal ground in degree measure is:
Option 1: 90°
Option 2: 60°
Option 3: 45°
Option 4: 30°
Correct Answer: 30°
Solution : Given: A kite is flying at a height of 50 metres. The length of the string is 100 metres. We know that $\sin\theta=\frac{\text{perpendicular}}{\text{hypotenuse}}$ $\text{Hypotenuse}$ = 100 m $\text{Perpendicular}$ = 50 m ⇒ $\sin\theta=\frac{50}{100}$ ⇒ $\sin\theta=\frac{1}{2}$ ⇒ $\sin\theta=\sin30°$ ⇒ $\theta=30°$ Hence, the correct answer is 30°.
