Write a menu driven program that achieves the following:
- Takes student’s information from the user and adds such a student into Mark Sheet.
- Takes a student number from the user and update such a student’s information.
- Takes a student number from the user and delete such a student from Mark Sheet.
- Generate or re-generate individual student report files.
- Write a short report on the approach you used to solve the problem in hand.
A battery having a voltage source of cos t is connected to a series circuit on which the
inductance is 0.75 henry and the resistance is 15 ohms. Determine the current i at any time t if the
initial current is zero.
A large tank initially contains 220 gal of brine where there is dissolved 35lb of salt. Starting
at time t = 0, a brine containing 3lb of dissolved salt per gallon flows into the tank at the rate of
6gal/min is kept uniform by stirring and the well-stirred mixture simultaneously flows out of the
tank at a slower rate of 3gal/min. How much salt is in the tank at the end of 20 min?
reverse bending stress of 300 N/mm2 is acting on 55 mm diameter steel. the ultimate strenth of steel is 590 N/mm2. Consider the factors ka= 0.45,Kb=0.85,Kc=0.89 and remaining factor are 1. Calculate the life of the bar for the reliability of 90%.
According to the data listed at the Philippine Statistics Authority, the Philippine total
population reached 4 billion persons in year 2020 and was then increasing at the rate of 250
thousand persons each day. Assuming that natural population growth at this rate continues, what
will be the population at year 2060?
Consider the lot of fluorescent tubes in number 100.if 50 samples of 100 tubes are drawn from the lot with replacement find the expected number of sample will have mean life atleast 1600 hrs. Flourescent tubes are 1570 hrs with a s.d. of 150 hrs.
You are the curator of a museum. The museum is running short of funds, so you decide to increase revenue. Should you increase or decrease the price of admission? Explain.
A spinner for a child's game has the numbers 1 through
9 evenly spaced. If a child spins, find each probability:
a. The number is divisible by 3.
b. the number is greater than 7.
c. The number is an even number.

1. Greater consumption of alcohol leads to more motor vehicle accidents and, thus, imposes costs on people who do not drink and drive.
a. Illustrate the market for alcohol, labeling the demand curve, the social-value curve, the supply curve, the social-cost curve, the market equilibrium level of output, and the efficient level of output.
b. On your graph, shade the area corresponding to the deadweight loss of the market equilibrium. (Hint: The deadweight loss occurs because some units of alcohol are consumed for which the social cost exceeds the social value.) Explain.
