Answer : 1. "TRUE"
Explanation :
Answer: A) TRUE Explanation: True, Water is a Pure substance and not a mixture. We know that, A mixture is when two or more substances combine physically together. You can find that the mixture retains the properties of the original components. In water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone. Therefore, water is not a mixture; it is a compound and it is pure.

Answer : 3. "Any two of (1, 2 & 3)"
Explanation :
Answer: C) Any two of (1, 2 & 3) Explanation: Using Both 1 & 2 statements we get the rate of interest as in (1) we have given principle amount and in (2) compound interest for 2 years. By this data we get the rate%. Using Both 1 & 3 statements we can get the rate% as we have principle amount & difference between compound interest and simple interest in 2 years. Using Both 2 & 3 statements we get compound interest & simple interest by which we get principle amount. So that we can calculate %rate. Hence by using any two of the three statements(1,2&3) we get rate of interest.
