The following table gives the average prices per quarter of vegetables over 2 years. In which quarter was the difference in price maximum?
| price per kg (in ₹) year 1 | price per kg (in ₹) year 2 | |
| quarter 1 | 36 | 40 |
| quarter 2 | 80 | 80 |
| quarter 3 | 65 | 40 |
| quarter 4 | 43 | 40 |
To find the quarter with the maximum difference in price, we need to calculate the absolute difference between the price per kg in Year 1 and Year 2 for each quarter. Then, we compare these differences to identify the maximum value.
D) quarter 3 — The difference in price for Quarter 3 is \( |65 - 40| = 25 \), which is the highest among all quarters.

This problem involves ratios and mixtures. We will set up equations based on the initial ratio, the removal of a part of the mixture, the addition of liquid B, and the final ratio. We'll use a variable to represent the initial total quantity of the mixture and then solve for the amount of liquid A.
Initial State: Let the initial total quantity of the mixture in the bucket be \(12x\) liters (since the ratio of A:B is 7:5, the sum of ratio parts is \(7+5=12\)).
Removing the Mixture: 9 liters of the mixture is removed. When a mixture is removed, the liquids are removed in the same ratio as they are present in the mixture.
Quantities after removal:
Adding Liquid B: 10 liters of liquid B is added to the mixture.
Final Ratio: The ratio of liquid A to liquid B becomes 7:9.
So, we can write the equation:
\[ \frac{7x - \frac{21}{4}}{5x + \frac{25}{4}} = \frac{7}{9} \]Solve for \(x\):
Cross-multiply:
\[ 9 \left( 7x - \frac{21}{4} \right) = 7 \left( 5x + \frac{25}{4} \right) \]\[ 63x - \frac{189}{4} = 35x + \frac{175}{4} \]Group terms with \(x\) and constant terms:
\[ 63x - 35x = \frac{175}{4} + \frac{189}{4} \]\[ 28x = \frac{175 + 189}{4} \]\[ 28x = \frac{364}{4} \]\[ 28x = 91 \]Solve for \(x\):
\[ x = \frac{91}{28} \]\[ x = \frac{13}{4} \]Calculate the initial quantity of liquid A:
Initial quantity of liquid A was \(7x\).
\[ \text{Initial A} = 7 \times \frac{13}{4} = \frac{91}{4} \]\[ \text{Initial A} = 22.75 \text{ liters} \]B) 22.75 is the correct answer. This matches our calculated initial quantity of liquid A.
This is a blood relations question. We need to break down the statement made by Naina step-by-step, starting from the end of the statement and working backward to identify the relationship.
