Three types of tea the a,b,c costs Rs. 95/kg,100/kg and70/kg respectively.How many kgs of each should be blended to produce 100 kg of mixture worth Rs.90/kg, given that the quantities of band c are equal  Choose the correct choice from the following choices
A) 70,15,15
B) 50,25,25
C) 60,20,20
D) 40,30,30
E) 20,30,30
given quantities of b and c are equal .   therefore instead of considering them as a different quantities take average of both and consider it as a single entity .   so the cost of the mixture "D" (equal quantities of "B" and "C") is  170/2=

<output>85</output>
85rs/kg   now the tea contains only "A" of 95 rs/per and "D" of 85 rs/kg.   it is clearly seen that "A" is 5 more and "D" is 5 less than the required cost per kg .   therefore 50/50 will go well .   A=50kg and D=50kg. (D= B&amp;C in equal ratio). therefore BC=25kg each .   (A:50,25,25:C)=(50,25,25)   ANSWER:50,25,25
