Select the option that is true regarding the following labelled Assertion (A) and Reason (R): Assertion (A): The cost of 3 vadas and 4 samosas is ₹195. If the cost of a samosa increases by 10% and that of a vada decreases by one-fifth, the cost of 2 vadas and 3 samosas is ₹139. The original cost of 2 vadas and 1 samosa is ₹80. Reason (R): Let the cost of 1 vada and 1 samosa be ₹x and ₹y, respectively. Then 3x + 4y = 195 and 2 × (1.1)x + 3 × 15y = 139.
