Orange Density Experiment

In single slit experiment, if green light is instead of orange light then width of fringe will

In Young's double slit experiment, if the source of light changes from orange to blue then :

During an experiment, an ideal gas is found to obey a condition (p^2)/(rho) = "constant" . ( rho = density of the gas). The gas is initially at temperature (T), pressure (p) and density rho . The gas expands such that density changes to rho//2 .

If the cost price of 15 oranges is equal to the selling price of 20 oranges, the loss percent is:

Four bad oranges are mixed accidently with 16 good oranges.Find the probability distribution of the number of bad oranges in a draw of two oranges.

The selling price of 10 oranges is the cost price of 13 oranges. Then the profit percentage is

In Boyles experiment for a given gas at different temperature the graph drawn between pressure and density are straight lines as shown then
