If 4 men and 6 women earn 1600 in 5 days and 3 men and 7 women earn 1740 in 6 days them in what time will 7 men and 6 women earn 3760

• Ans=8 Days
  If Earning of Men=M, Women=W
  1 day earning of 4M+6W=1600/5=320 ---(i)
  1 day earning of 3M+7W=1740/6=290 ---(ii)
  Solving (i) & (ii), M=50,W=20
  1 day earning of 7 men and 6 women=7*50+6*20=470
  So Rs. 3760 will be earned in 3760/470=8 days

• 4x+6y=1600/5=320
  3x+7y=1740/6=290
  solve
  x=50
  y=20
  so 7x+6y=470 ans.........
