Question : S1 and S2 can do a piece of work together in 18 days, S2 and S3 can do the same work together in 27 days, while S3 and S1 can do it together in 54 days. In how many days can all 3, working together, do 50% of the work?
Option 1: 8 days
Option 2: 6 days
Option 3: 7 days
Option 4: 9 days

Question : If $a^2+b^2+c^2=a b+b c+a c$, then the value of $\frac{11 a^4+13 b^4+17 c^4}{17 a^2 b^2+9 b^2 c^2+15 c^2 a^2}$ is:
Option 1: 1
Option 2: 2
Option 3: 11
Option 4: 4
Correct Answer: 1
Solution : Given: $a^2+b^2+c^2=a b+b c+a c$ Multiplying both sides with 2, we get: $2a^2+2b^2+2c^2=2ab+2bc+2ac$ ⇒ $a^2+b^2-2ab+b^2+c^2-2bc+c^2+a^2-2ac=0$ ⇒ $(a-b)^2+(b-c)^2+(c-a)^2=0$ So, $a-b=0$, $b-c=0$, $c-a=0$ ⇒ $a=b=c$ Now, $\frac{11 a^4+13 b^4+17 c^4}{17 a^2 b^2+9 b^2 c^2+15 c^2 a^2}$ $=\frac{11 a^4+13 a^4+17 a^4}{17 a^2 a^2+9 a^2 a^2+15 a^2 a^2}$ $=\frac{41
