Question

Answer is 9 per kg given in the book...​

Answer 1

Answer:

Answer is ₹9 per kg

Step-by-step explanation:

Total Quantity of the Rice he has:

80+120 = 200kg.

Total money he spent to buy the rice:

6.75 × 80 + 120 × 8 = ₹1,500.

He needs to have a gain of 20% so,

20% of 1,500 is his gain/profit.

20/100 × 1,500 = ₹300.

Adding it to the money he spent to buy the rice:

₹1,500 + ₹300 = ₹1,800.

₹1,800 is the money he will get by selling 200kg of rice @ 20% gain.

So, in order to get this gain, he has to sell it @

1,800/200 = ₹9//

₹9 per kilogram of rice.

hope it helps god bless :)
