Option 1: 78
Option 2: 90
Option 3: 85
Option 4: 80
Correct Answer: 80
Solution : Average sale of cars (from all branches) for the year 2018 = $\frac{80+75+95+85+75+70}{6}$ = $\frac{480}{6}$ = 80 Hence, the correct answer is 80.
Question : If $a=331, b=336$ and $c=–667$, then the value of $a^3+b^3+c^3–3abc$ is:
Option 1: 1
Option 2: 63
Option 3: 3
Option 4: 0
Correct Answer: 0
Solution : $a^3+b^3+c^3-3abc=(a+b+c)(a^2+b^2+c^2-ab-bc-ca)$ If $a+b+c=0$, then $a^3+b^3+c^3-3abc=0$ Here $a+b+c= 331+336-667=0$ So, $a^3+b^3+c^3-3abc=0$ Hence, the correct answer is 0.
