Question : If $(a+b+c) \neq 0$, then $(a+b+c)\left(a^2+b^2+c^2-a b-b c-c a\right)$ is equal to:
Option 1: $a^3+b^3-c^3-3abc$
Option 2: $a^3-b^3+c^3-3abc$
Option 3: $a^3+b^3+c^3-3abc$
Option 4: $a^3+b^3+c^3+3abc$
Correct Answer: $a^3+b^3+c^3-3abc$
Solution : Given: $(a+b+c)\left(a^2+b^2+c^2-ab-bc-ca\right)$ Simplifying this expression, we have: $(a^3+ab^2+ac^2–a^2b–abc–ca^2+a^2b+b^3+bc^2–ab^2–b^2c–abc+a^2c+b^2c+c^3–abc–bc^2–c^2a)$ = $(a^3+b^3+c^3–3abc)$ Hence, the correct answer is $(a^3+b^3+c^3–3abc)$.

Question : Study the given table and answer the question that follows. The table shows the consumption of various grains by four families of four members each from 2002 to 2005.
For the total of these four families, what is the difference (in kg) between the average consumption per year of wheat and that of oats?
Option 1: 129.5
Option 2: 90.67
Option 3: 70.75
Option 4: 63.5
Correct Answer: 70.75
Solution : Average consumption per year of wheat = $\frac{162 + 196 + 187 + 189}{4}$ = $\frac{734}{4}$ = 183.5 Average consumption per year of oats = $\frac{131 + 116 + 103 + 101}{4}$ = $\frac{451}{4}$ = 112.75 $\therefore$ Difference = 183.5 – 112.75 = 70.75 Hence,
