Question

Two friends Harry and Larry who are very fond of Indian cuisine went to Hotel $A$ for having lunch. Harry and Larry had $3$ and $5$ rotis respectively. For dinner they went to Hotel $B$ where the size of the roti was relatively small. Assuming that they have same amount of hunger as before and Larry ate $10$ rotis, how many rotis did Harry eat?

• A. $6$
• B. $7$
• C. $8$
• D. $9$

Answer 1

The correct option is A

$6$

Let rotis eaten by Harry for dinner be $x$

If they have the same amount of hunger, the ratio of rotis eaten by them will remain same in both the hotels.

Hence, $\frac{3}{5}=\frac{x}{10}$

$\Rightarrow x=\frac{10\times 3}{5}$

$\Rightarrow x=6$

So, Harry ate $6$ rotis.
