A tank is in the form of a cuboid with length 12 m. If 18 kilolitre of water is removed from it, the water level goes down by 30 cm. What is the width (in m) of the tank?
A. 5
B. 4.5
C. 4
D. 5.5
Answer: Option A
Solution (By Examveda Team)
Volume of cuboid = $$l$$bh12 × b × h - 18 = 12 × b × (h - 0.3)
12bh - 18 = 12bh - 3.6b
b = 5 m
