Question

a cabbage costs Rs 20 more than a water melon. the cost of two cabbages and four watermelons are Rs 340. what is the cost of one water melon
​

Answer 1

Let the cost of water melons be x

Cost of cabbage = x + 20

Cost of four watermelon and 2 cabbages = 340

x+x+x+x + (x+20)+(x+20) = 340

4x + 2x + 40 = 340

6x + 40 = 340

6x = 340-40

6x = 300

x = 300/6

x = 50

Cost of 1 Watermelon = Rs.50

Cost of 1 Cabbage = x + 20 = 50 + 20 = Rs.70

watermelon cost is is 20 rupees
