Answer 2

Answer:

The amount of chocolate to be mixed is 168 kg.

Step-by-step explanation:

Let the amount of chocolate to be mixed be x

So, the total cost of the chocolate to be added = Rs. 40x

Amount of coffee= 120 kg

Price of coffee/kg = Rs.100

So, total cost of the coffee = Rs. 12000

According to the conditions given,

65( x + 120) = 40x + 12000

So, 25x = 12000-7800 = 4200

So, x= 168 kg

Hence, the amount of chocolate to be mixed is 168 kg.
