The density of milk at 25°C is 1000 g/litre and it varies with temperature according to the following relation:
dt = 2500 – kt, where dt = density of milk (at temperature t) in g/litre, t = temperature in °C and k is a constant.
A milkman buys milk from a place where the temperature is 25°C and sells it at a place where the temperature is 30°C. If he claims to buy and sell milk at the same price (in Rs./litre), then what is the profit made by him? (It is given that mass of the milk is independent of its density and temperature ..
During one of the shows in ‘Jemini’ circus, four hats are picked randomly from a trunk that contains 3 red hats, 5 black hats, 4 blue hats and 6 yellow hats, and are given to four dwarfs such that each dwarf gets exactly one hat. All the dwarfs throw their hats in the air simultaneously. Then each dwarf comes under exactly one of the hats, not necessarily the one thrown by him, such that the hat fits snugly on his head. What is the probability that at least two dwarfs are wearing the hats of same colour now and no dwarf has the same hat on his head that he had thrown in the air?
