Echina grows in the form of circle, and the relationship between the diameter of this circle and the age of echina is given by the formula d = 4*[sqrt(t-9)] for t>9, where d represents the diameter in mm and t the number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur?

(#M40000831) TCS QUESTION tcs recent question Keep an EYE

A boy wants to make cuboids of dimension 5m, 6m and 7m from small cubes of .03 m3. Later he realized he can make same cuboids by making it hollow. Then it takes some cubes less. What is the number of the cubes to be removed?
a) 2000 b) 5000 c) 3000 d) 7000

Solution

volume of the small cube = 0.03 m^3
so side of this cube = cubic root of 0.03 m^3 = .312 m
so after removing the outermost layer the dimensions for the inner cuboid will be (5-2*0.312), (6-2*0.312), (7-2*0.312)
so total volume will be (4.376)*(5.376)*(6.376) = 150 m^3
so no of cubes will be 150/0.03 = 5000
so we can remove 5000 inner cubes
