George purchased leeks,beet,carrot and radish for Rs.130/= and 500g of each vegetable.cost of leeks and beet are same, cost of carrot is Rs.10/= more than the cost of beet, cost of radish is Rs.10/=less than the cost of carrot. what is the cost of 500g of leeks?
Note that all vegetables' weights are the same: 500g
Let cost of 550g of leeks, beets, carrots, and radish, be L, B, C, and R, respectively
We then get: B = L ----- eq (i)
C = B + 10____C = L + 10 ------ eq (ii)
R = C - 10_____R = L + 10 - 10_____R = L ------- eq (iii)
With total cost being Rs 130, we have: B + L + C + R = 130 ------ eq (iv)
L + L + L + 10 + L = 130 ------ Substituting L for B, L + 10 for C, and L for R
4L + 10 = 130
4L = 120
L, or cost of 500g of leeks =
