Question

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 quntities of band c are equal

Answer 1

Let the amount of each tea :

A = x

B = (100 - x) /2

C = 50 - 1/2x

Total price :

95x + 100 (50 - 0.5x) + 70(50 - 0.5x) = 100 × 90

95x + 5000 - 50x + 3500 - 35x = 9000

95x - 85x = 9000 - 8500

10x = 500

x = 50 kgs

A = 50 kgs

B = 50 - 0.5 × 50 = 25 kgs

C = 25 kgs
