Three types of tea (namely a, b and c) costs Rs. 95/kg, Rs. 100/kg and Rs. 70/kg respectively. How many Kg. of each should be blended to produce 100 kg of mixture worth Rs. 90/kg, given that the quantities of band c are equal ?
A. 70,15,15 B. 50,25,25 C. 60,20,20 D. 40,30,30

• B 50,25,25
  
  Total cost should be Rs 9000/-.
  Average cost of B and C = (100+70)/2= Rs 85
  
  For making average cost of A,B and c equal to Rs 95, quantity of A should be equal to sum of quantity of B and C.
  50*95+25*(100+70) = 25*(190+170) = 25*360= Rs 9000/-.

• 90*100=9000
  50*95=4750
  25*100=2500
  25*70=1750
  4750+2500+1750=9000, so option B is correct
