107.5 grams of total quantity has 100 gm of actual grains.
Mohan purchases 5 kg of each type. Actual grains in 10 gm = (10 * 100)/107.5 ⇒ 9.3 So, the required percentage = 93

To solve this problem, we need to determine the percentage of actual grain in the rice purchased by Mohan.

Let's break down the problem into smaller steps:

Step 1: Calculate the total weight of rice purchased by Mohan.
Mohan purchases 5 kg of each variety of rice, so the total weight of rice purchased is 5 kg + 5 kg = 10 kg.

Step 2: Calculate the total weight of stones in the rice.
The grocer mixes 100 grams of stones per kg of the first variety of rice and the remaining stones in the second variety. Since Mohan purchases equal amounts of both varieties, we can calculate the total weight of stones as follows:

Total weight of stones = (100 grams/kg x 5 kg) + (1000 grams/kg x 5 kg) = 500 grams + 5000 grams = 5500 grams

Step 3: Calculate the total weight of rice and stones.
The total weight of rice and stones is the sum of the weight of rice and the weight of stones:

Total weight of rice and stones = (10 kg + 10 kg) + 5500 grams = 20 kg + 5500 grams

Step 4: Calculate the percentage of actual grain in the rice.
To calculate the percentage of actual grain, we need to subtract the weight of stones from the total weight of rice and stones and then divide by the total weight of rice and stones, and finally, multiply by 100 to get the percentage:

Percentage of actual grain = [(Total weight of rice and stones - Total weight of stones) / Total weight of rice and stones] x 100

Substituting the values, we get:
Percentage of actual grain = [(20 kg + 5500 grams - 5500 grams) / (20 kg + 5500 grams)] x 100
= [(20 kg) / (20 kg + 5500 grams)] x 100
= [(20 kg) / (20 kg + 5.5 kg)] x 100
= [(20 kg) / (25.5 kg)] x 100
= 78.43

Since we are asked to round off the answer to the nearest integer, the approximate percentage of actual grain is 78.

Therefore, the given answer of 93 is incorrect. The correct answer is 78.
