MSTE Nov 2021 Civil Engineering Past Board no 9 to 17

Past Civil Engineering Board Exam in Mathematics, Surveying and Transportation Engineering in Nov. 2021. These are #9 to #17 MSTE CE Board Nov. 2021 multiple-choice questions are answered and/or solved. Questions include: inversely proportional, operation of matrix, familiarity of how equations are used and snell's law. I will give my thoughts about the problems and how I solved them. I also give tips and tricks along the way.

9. The measure of the largest angle of a triangle is 80 degrees more than the measure of the smallest angle, and the measure of the remaining angle is 10 degrees more than the measure of the smallest angle. Find the measure of each angle.
10. A time study showed that the average time taken to deal with car insurance request by BPO agents in Manila, was 6 minutes. The analyst rated the observed worker at 90%, meaning the worker performed at 90% of basic time when the observed were made. the firm has an allowance factor of 8%. Calculate the basic and standard time for the operation. Hint: Basic time = (Average observed time x Performance rating factor) & time - Basic time/ 1 - Allowance factor
11. It occurs as concrete hardens, being greater in wet mixes. Curing helps to limit effects and therefore concrete in the actual structure should be thoroughly and continuously moistened for some considerable period after placing.
12. The area of the sector AOB with point O as its center is equal to 96pi having a radius of 24 m. A small circle is inscribed in the sector which is tangent to all the three sides of the sector. Find the radius of the small circle inscribed in the sector.
13. A message will be transmitted from terminal A to terminal B if the relays R1, R2, R3 and R4 are closed. If the probabilities of these relays are closed as respectively, 0.5, 0.7, 0.8 and 0.8, find the probability that message will get through. Assume that the relays function independently.
14. Your engineering group just finished the preliminary design of a small refinery. The estimated cost is Php19 million for a capacity of 2 million barrels per year. Your management has asked you for order-of-magnitude estimates for facilities with capacities of 1 million and 3 million barrels per year. Compute the cost per barrel capacity.
15. A lighthouse shows successive one-second flashes of red, white, green, white, red. A second lighthouse does the same only with two-second flashes. The six-second sequence of the lighthouse is repeatedly steadily as is the twelve-second sequence of the other lighthouse. What fraction of the time do the two lights, show the same color if the given sequences start at the same time?
16.A topographic surveying map using a scale 1 cm = 40 m, and with a contour interval of 1.0 m, the distance scaled on the map between two adjacent contours is 15 mm. Determine the slope of the ground in percent.
17. The single initial application of bituminous material to an existing bituminous, Portland concrete, or block surface or base is called:
