Answer: The answer is 5 kgs.
Step-by-step explanation: Let the quantity of rice @ rs 10/kg to be added to 25 kgs of rice @ rs 8/kg be 'h' kgs.
Therefore, total price of the mixture = 10×h + 25×8 = rs (10h+200).
At the time of selling, total quantity = (h+25) kgs.
Since we are selling @ 15/kg, so the selling price of the mixture
= rs 15×(h+25).
Also, we are making a profit of 80%, hence we have
Thus, the required quantity of rice to be added is 5 kgs.
