A boy lives at X and wants to go to school at Z. From his home to X he has to first reach Y
and then Y to Z. He may go X to Y by either 3 bus routes or 2 train routes. From there, he can
either choose 4 bus routes or 5 train routes to reach Z. How many ways are there to go from X to
Z?
Suppose there are 19 Math majors, 17 English majors, and no double majors. How many ways
are there to choose someone who is either a Math major or a English major?
Explain how the fundamental economic problem is addressed in a planned economy and in a
market economy
The thin-walled single cell beam shown in Figure has been idealized into a combination of
direct stress carrying booms and shear stress only carrying walls. If the section supports a vertical
shear load of 10 kN acting in a vertical plane through booms 3 and 6, calculate the distribution of
direct stress around the section.

If a farmer is chosen randomly from this community, what is the probability that he grows neither oranges nor lemon
describe how chlorine gas is produced in electrolysis
Steam at a temperature of 623 K is flowing through a pipe with an outer diameter of 100 mm. The pipe is insulated with 20-mm thick mineral wool, the average thermal conductivity of which is 0.055 W/m.K. Determine the outside surface temperature of mineral wool if the ambient air temperature is 300 K. Assume the hot-surface temperature of the mineral wool is the same as that of the flowing steam and the value of the surface coefficient of the insulating material is 30 W/m2.K.
