Speed varies with time taken as well as distance covered. However, whether the variation is direct or inverse is not known. All the three parameters are raised to the same power. In one case, time taken increase by 50% and distance increases by 20%. Which of following statements can be true?
i. Speed increases by 80%
ii. Speed decreases by 20%
iii. Speed neither increases nor decreases
iv. Speed increases by 25%
  • a)
    i and ii
  • b)
    Only ii
  • c)
    i, ii, iv
  • d)
    All the statements are true
Correct answer is option 'C'. Can you explain this answer?

Let original time taken and distance covered be t and d respectively.
New Time = 1.51
New Distance = 1.2d
New speed (S) can vary in the following ways, 
Thus, statements i, ii and iv can be true. Hence, option 3.

The question provides information about the variation of speed with time taken and distance covered. It states that the variation can be either direct or inverse but does not specify which one it is. Additionally, it mentions that all three parameters (speed, time taken, and distance covered) are raised to the same power.

To analyze the given scenario, we can consider the following:

1. Let's assume that the variation between speed and time taken is direct. This means that as time taken increases, speed also increases. In this case, when time taken increases by 50%, speed will increase by 50% as well. However, since the variation between speed and distance covered is unknown, we cannot determine the effect of a 20% increase in distance on speed. Therefore, we cannot conclude whether any of the statements are true.

2. Now, let's assume that the variation between speed and distance covered is direct. This means that as distance covered increases, speed also increases. In this case, when distance covered increases by 20%, speed will increase by 20% as well. However, since the variation between speed and time taken is unknown, we cannot determine the effect of a 50% increase in time taken on speed. Therefore, we cannot conclude whether any of the statements are true.

3. Finally, let's assume that the variation between speed and both time taken and distance covered is inverse. This means that as time taken or distance covered increases, speed decreases. In this case, when time taken increases by 50%, speed will decrease by 50%. Similarly, when distance covered increases by 20%, speed will decrease by 20%. Since both increases result in a decrease in speed, we can conclude that statement ii is true.

In conclusion, based on the given information, only statement ii (Speed decreases by 20%) can be true. The other statements cannot be determined due to the unknown variation between speed and the other parameters.

A survey was carried out to assess the acceptability of private insurance players. A group of 100 respondents was identified and they were to be queried on the following parameters : Reliability, Claim Settlements and Ethical Sales. The insurance companies to be surveyed were camouflaged as C1, C2, C3 and C4. The query was based on two factors: Acceptable and Non-acceptable. The chart below gives the details of the respondents who answered the queries as acceptable for the said parameters.In the above chart, 1 does not necessarily represent C1. Similarly 2 may or may not represent C2. Also, the three parameters of 1 may not necessarily stand for the same company. For. eg: Reliability of 1 could be of company C1while Claim Settlement of 1 could be of Company C2.It was further observed that a single respondent had answered only one query on any one parameter i.e. no respondent had answered to two parameters that were asked for in the survey.Further1. The total number of respondents who had accepted the companies C2 and C4 on all the parameters was 29 and 26 respectively.2. C3 had equal number of respondents accepting it on at least two of the parameters and further the total number of respondents that C3 had on all the parameters was greater than the total number of respondents who had accepted C1 on all parameters put together.3. C1 had witnessed different number of respondents for each of the three parameters.4. C2 did not have 10 or 5 respondents giving a positive reply for any of the parameters.Further to have a more comprehensive analysis of the survey a point system was adopted wherein the company for whom the number of respondents for any particular parameter was highest was awarded 5 points. Similarly, the company which witnessed second highest number of respondents for that same parameter was awarded 3 points, third highest was awarded a single point and the company which had the least number of respondents accepting it on that particular parameter was supposed to get zero points.Q. Which of the following combinations of statements can be true?1. The ratio of number of respondents that had accepted C2 and C4 on Ethical Sales is 7 : 5.2. The ratio of number of respondents that had accepted C2 and C4 on Ethical Sales is 7 : 8.3. The ratio of number of respondents that had accepted C3 and C4 on Claim Settlement is 2 : 1.4. The ratio of number of respondents whohad accepted C3 and C1 on R eliability is 2 : 5 or 5 : 2.
