man buys two cows for 1350.sell one at a loss of 6% and other at a gain of 7.5%.on the whole heneither loss nor gain..first cow cost?

• Let x nd y be the cost of 2 cows
  Then
  x + y = 1350
  0.94x + 1.075y = 1350
  x = 1350 - y
  0.94(1350-y) + 1.075y = 1350
  1269 - 0.94y + 1.075y = 1350
  y = 600
  x = 750
  
  Ans : 750
