A shepherd has 1 million sheep at the beginning of Year  2000. The numbers grow by $x% (x > 0)$ during the year. A famine hits his village in the next year and many of his sheep die. The sheep population decreases by $y%$ during 2001 and at the beginning of 2002 the shepherd finds that he is left with 1 million sheep. Which of the following is correct?


$x > y$


$y > x$


$x = y$


Cannot be determined

Option(A) is correct

Let us assume the value of $x$ to be $10\%$.

Therefore, the number of sheep in the herd at the beginning of year 2001 (end of 2000) will be 1 million + $10\%$ of 1 million = 1.1 million

In 2001, the numbers decrease by $y\%$ and at the end of the year the number sheep in the herd = 1 million.
i.e., 0.1 million sheep have died in 2001.

In terms of the percentage of the number of sheep alive at the beginning of 2001,

it will be $(0.1/1.1)\times 100 \% = 9.09\%$.

From the above illustration it is clear that $x > y$

there should be a correction in the question..x% and y%..instead of x and y..else it can be interpreted as numeric values

Its easy to understand with this assumption
