Question 72
Ravi spent less than Rs. 75 to buy one kilogram each of potato, onion, and gourd. Which one of the three vegetables bought was the costliest?
A. 2 kg potato and 1 kg gourd cost less than 1 kg potato and 2 kg gourd.
B. 1 kg potato and 2 kg onion together cost the same as 1 kg onion and 2 kg gourd.
Solution
Using statement 1 alone, 2P + G < P + 2G
=> P < G
Using statement 2 alone, P + 2O = O + 2G
=> P + O = 2G
So, using either statement alone, we cannot find the answer to the question.
However, by using both the statements together, we can determine that P < G < O
So, option c) is the answer.
