Volume of a water tank is 192 cft. Its length, breadth, and height are in proportions 4:3:2--- What is the area of its base in square feet?
Solution
Correct Answer: Option C
suppose, length 4x, breadth 3x and height 2x
here, 4x . 3x . 2x =192
or,24x3=192
or,x3=8
or,x=2
so, length= 4X2=8 m
wide= 3X2=6 m
breadth=2X2=4m
so,base area=8 X 6=48 sq m
