A man 'Ramesh', who owns a plot of land of 100 square yards, increases his plot of land by acquiring 10% more from his neighbour 'Suresh', who also owns 100 square yards land. After 2 years, he sells back 10% of the total plot to the neighbour. Which of the following is correct?
Answer: B
The answer is Suresh's land is more than Ramesh.
Ramesh acquires 10% of Suresh's 100 square yards, 10 square yards, so Ramesh has 110 and Suresh 90. Later Ramesh sells back 10% of his total plot of 110, which is 11 square yards:
\[ \begin{aligned} \text{Ramesh} &= 110 - 11 = 99 \\ \text{Suresh} &= 90 + 11 = 101 \end{aligned} \]
Suresh ends with 101 square yards and Ramesh with 99, so Suresh has more. They are not equal because 10% of 110 is more than the 10 that changed hands first.
