Read the text carefully and answer the questions:
Mohan wants to donate a rectangular plot of land for a hospital in his village. When he was asked to give dimensions of the plot, he told that if its length (x) is decreased by 50 m and breadth (y) is increased by 50 m, then its area will remain same, but if length is decreased by 10 m and breadth is decreased by 20 m, then its area will decrease by 5300 m2.
The value of the expression $\frac{x^2+y^2}{x-y}$ is:
Answer & explanation
Correct answer: option 2
We have got x = 200, y = 150
So $\frac{x^2+y^2}{x-y} = \frac{200^2+150^2}{200-150}=\frac{40000+22500}{50}$
$=\frac{62500}{50} = 1250$
Option: 2
