Direction : The distance (in km) between the home and shop in numerical value is equal to seven more than ¹⁄₃rd of square root of ¹⁄₁₁th of the capacity of the cylindrical jar and the speed of the man is four times of the time taken by him to reach the shop.
Speed of man _________kmph.
A man is going shop from his home with the speed of_______ kmph and time taken to reach the shop by him is _______ hours. After reaching there he purchases a cylindrical jar of certain height having capacity equal to 83259 cm³. The man also purchases a conical vessel whose capacity is 1/27th of cylindrical jar and height of conical vessel is 14 cm.
Note: Height of conical vessel is four times of the height of cylindrical jar
Answer: A. 12 — One-eleventh of the cylindrical jar capacity is 83259 / 11 = 7569. The square root is 87, and one-third of that is 29. Distance = 7 + 29 = 36 km. If time is t…

Show answer & explanation
Correct answer: A
One-eleventh of the cylindrical jar capacity is 83259 / 11 = 7569.
The square root is 87, and one-third of that is 29.
Distance = 7 + 29 = 36 km.
If time is t hours, speed = 4t and distance = 4t^2 = 36, so t = 3 and speed = 12 kmph.
