Question

in what proportion should tea at ₹47.50 per kg be mixed with tea at ₹50.50 per kg to produce a mixture worth ₹48.5 per kg ? ​

Answer 1

Answer:

Suppose the first type of tea is 62 x

Second type of tea is 72 y.

The mixture of two tea should cost Rs. 64.50

So x+y == 64.50 x

Therefore 62x + 72 y == 64.50 x

or 72 y == 64.50 x— 62 x

72y-64.50 == 64.50 x—62x

7.5 y ==2.5x

x/y ==3

Therefore 62*3 + 72*1==64.50 (3+1)

So there should be three kilogram of tea of Rs. 62 cost mixed with one kilogram of tea of cost Rs. 72 to get tea with the cost of Rs. 64.50.
