The difference between a two-digit number and the number obtained by interchanging the digits is 36. What is the difference between the sum and the difference of the digits of the number if the ratio between the digits of the number is 1 : 2 ?
Correct Answer
B. 8
Explanation
Since the number is greater than the number obtained on reversing the digits, so the ten's digit is greater than the unit's digit.
Let ten's and unit's digits be 2x and x respectively.
Then, (10 x 2x + x) - (10x + 2x) = 36
9x = 36
x = 4.
Required difference = (2x + x) - (2x - x) = 2x = 8.

A, B and C jointly thought of engaging themselves in a business venture. It was agreed that A would invest Rs. 6500 for 6 months, B, Rs. 8400 for 5 months and C, Rs. 10,000 for 3 months. A wants to be the working member for which, he was to receive 5% of the profits. The profit earned was Rs. 7400. Calculate the share of B in the profit.
Correct Answer
B. Rs. 2660
Explanation
For managing, A received = 5% of Rs. 7400 = Rs. 370.
Balance = Rs. (7400 - 370) = Rs. 7030.
Ratio of their investments = (6500 x 6) : (8400 x 5) : (10000 x 3)
= 39000 : 42000 : 30000
= 13 : 14 : 10
B's share = Rs. 7030 x 14 = Rs. 2660.

Two pipes A and B together can fill a cistern in 4 hours. Had they been opened separately, then B would have taken 6 hours more than A to fill the cistern. How much time will be taken by A to fill the cistern separately?
Correct Answer
C. 6 hours
Explanation
Let's assume that pipe A can fill the cistern in x hours. According to the given information, pipe B would have taken (x+6) hours to fill the cistern if it was opened separately.
When both pipes are opened together, they can fill the cistern in 4 hours. This means that in 1 hour, they can fill 1/4th of the cistern's capacity.
In 1 hour, pipe A can fill 1/xth of the cistern's capacity, and pipe B can fill 1/(x+6)th of the cistern's capacity.
Since they can fill 1/4th of the cistern's capacity in 1 hour when opened together, we can set up the equation:
1/x + 1/(x+6) = 1/4
Solving this equation, we find that x = 6.
Therefore, pipe A will take 6 hours to fill the cistern separately.

Offsets are measured with an accuracy of 1 in 40. If the point on the paper from both sources of error (due to angular and measurement errors) is not to exceed 0.05 cm on a scale of 1 cm = 20 m, the maximum length of offset should be limited to
Correct Answer
B. 28.28 m
Explanation
The accuracy of 1 in 40 means that for every 40 units measured, there is a potential error of 1 unit. In this case, the scale is 1 cm = 20 m, so the maximum error allowed is 0.05 cm. To find the maximum length of offset, we can set up a proportion: 1 cm / 20 m = 0.05 cm / x. Solving for x, we find that x = 20 m. Therefore, the maximum length of offset should be limited to 20 m. However, none of the given options match this value, so the correct answer is "none of these."

For a closed traverse the omitted measurements may be calculated
Correct Answer
E. All the above.
Explanation
For a closed traverse, the omitted measurements can be calculated in various ways. The length of one side can be calculated using the other measurements and trigonometry. Similarly, the bearing of one side can be determined using the measurements of other sides. Additionally, both the length and bearing of a side can be calculated if the measurements of other sides are known. Lastly, the length or bearing of an adjacent side can be calculated using the measurements of other sides. Therefore, all of the mentioned options are correct and applicable for calculating the omitted measurements in a closed traverse.

The effective length of a compression member of length L held in position and restrained in direction at one end and effectively restrained in direction but not held in position at the other end, is
Correct Answer
A. L
Explanation
In this scenario, the effective length of the compression member is equal to its actual length, L. This is because it is held in position and restrained in direction at one end, which prevents any lateral movement or buckling. However, it is only effectively restrained in direction at the other end, meaning that it can still experience some lateral movement or buckling, but to a lesser extent compared to being completely unrestrained. Therefore, the effective length is still equal to the actual length, L.

In a liquid limit test, the moisture content at 10 blows was 70% and that at 100 blows was 20%. The liquid limit of the soil, is
Correct Answer
C. 65%
Explanation
The liquid limit of the soil can be determined by finding the moisture content at the point where the soil transitions from a liquid to a plastic state. In this case, the moisture content at 10 blows is 70% and at 100 blows is 20%. As the number of blows increases, the moisture content decreases. Therefore, the moisture content at the liquid limit is between 20% and 70%. The only option within this range is 65%, so that is the correct answer.

For given water content, workability decreases if the concrete aggregates contain an excess of
Correct Answer
E. All the above.
Explanation
The workability of concrete refers to its ability to be easily mixed, placed, and compacted. When the concrete aggregates contain an excess of thin particles, flat particles, elongated particles, or flaky particles, it can negatively affect the workability. Thin particles can increase the water demand and decrease the cohesion of the mixture, flat particles can reduce the compactability and increase the water demand, elongated particles can cause segregation and reduce the workability, and flaky particles can reduce the cohesiveness and increase the water demand. Therefore, if the concrete aggregates contain an excess of any of these particles, the workability will decrease.
