Explanation:

profit % = 25/100 = ¼
CP = 4 and profit = 1
SP = 5
Now , SP = 300
5———300
1———60
CP = 4 * 60 = R.240/kg
Rice 1————— Rice 2
200——————–260
————–240
20———————40
1:2
52 kg of the second quantity .
so Rice 1 : Rice 2 = 1*26 : 2 * 26= 26 : 52
So , 26 kg of Rice 1 is added in the mixture.

Hence, option 2 is the correct answer.
