Select the correct option regarding the given Assertion (A) and Reason (R). Assertion (A): The cost of 3 vadas and 4 samosas is Rs. 195. If the cost of a samosa increases by 10% and that of a vada decreases by one-fifth, then the cost of 2 vadas and 3 samosas becomes Rs. 139. The original cost of 2 vadas and 1 samosa is Rs. 80. Reason (R): Let the original cost of 1 vada and 1 samosa be Rs. x and Rs. y, respectively. Then, 3x + 4y = 195 and 2 × (0.8)x + 3 × (1.1)y = 139.
