How many kilograms of tea, worth 300/- Per Kg should be mixed with 10 Kg of tea worth 240/- per kg to produce a mixture to cost 260/- per kg.
To find: How many kilograms of tea, worth 300/- Per Kg should be mixed with 10 Kg of tea worth 240/- per kg to produce a mixture to cost 260/- per kg.\
Solution:
Let $y$ kg of tea worth Rs.300 be added,
Quantity of tea taken that was worth Rs.240 =10 kg
Total quantity of tea that will be produced after mix= $(10+y)$ kg
The final tea mixture should cost 260 per kg
Cost of tea = $240\times10 + 300\times y = 260\times(10+y)$
Solving the above, we get $y=5$.
Therefore, 5kg of tea worth Rs.300 should be added
