A tank is filled with x pounds of wheat. The tank has a hole at the bottom and each day 1% of the wheat is lost from the tank through the hole.
Quantity A |
Quantity B |
Percentage of wheat lost in the first three days |
3% |
A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
In this type of question since the deduction was for 3 times,
so the percentage of loss in first 3 times at 1% loss will be always less than 3% or percentage loss in 4times at 1% loss < 4%
Now
Percentage of wheat lost in the first three days = \(\frac{{x - (0.99 * 0.99 * 0.99)x}}{x} *100\) = 2.9
Hence QTYA < QTY B
Option is B
