A tank can be filled in by an inlet pipe of circular cross section in 10 min. Another tank twice as big is filled in by 3 inlet pipes whose diameters are in the ratio 1 : 2 : 3 . If the smallest pipe of these is four times as much in cross section as the pipe of the first tank, find the time taken to fill the second tank. [Speed of water in the second tank is half the speed of the water in the first tank.

There is a circle of radius 1 cm. Each member of a sequence of regular polygons S1(n),
n = 4, 5, 6, β¦, where n is the number of sides of the polygon, is circumscribing the circle: and each
member of the sequence of regular polygons S2(n), n = 4, 5, 6, β¦ where n is the number of sides of
the polygon, is inscribed in the circle. Let L1(n) and L2(n) denote the perimeters of the corresponding
polygons of S1(n) and S2(n), then
L2 (17)

City Care hospital provided vaccines for Polio to 500 children. It was found that 150 children were given a single dose of vaccine-A, 150 children were given a single dose of vaccine-B whereas 200 children were given a single dose of each of vaccine-A and vaccine-B. Each of the 500 children chosen has 60% chance of contracting polio. Vaccine-A reduces the probability of contracting polio by 20%, while vaccine-B reduces the probability by 30%. The two vaccines when given together, work independently. If a child, selected randomly from the chosen 500 children, contract polio then what is the probability that the selected child was given vaccine-A?
