Question : If (x – 8)2 – (x + 8)2 = 0. What is the value of x?
Option 1: 1
Option 2: 32
Option 3: 0
Option 4: –32
Correct Answer: 0
Solution : (x – 8)2 – (x + 8)2 = 0 ⇒ (x – 8 + x + 8)(x – 8 – x – 8) = 0 ⇒ (2x)(– 16) = 0 ⇒ x = 0 Hence, the correct answer is 0.
Question : If $a^2+b^2+c^2=ab+bc+ca$, then the value of $\frac{11a^4+13b^4+15c^4}{16a^2b^2+19b^2c^2+17c^2a^2}$ is:
Option 1: $1 \frac{1}{3}$
Option 2: $\frac{1}{4}$
Option 3: $\frac{3}{4}$
Option 4: $1 \frac{3}{4}$
Correct Answer: $\frac{3}{4}$
Solution : Given: $a^2+b^2+c^2=ab+bc+ca$ So, $2a^2+2b^2+2c^2-2a b-2b c-2c = 0$ ⇒ $(a-b)^2+(b-c)^2+(c-a)^2=0$ If some of the positive terms are 0, the terms are themselves 0. ⇒ $(a-b)=(b-c)=(c-a)=0$ ⇒ $a=b=c$ So, $\frac{11a^4+13b^4+15c^4}{16a^2b^2+19b^2c^2+17c^2a^2}$ = $\frac{11a^4+13a^4+15a^4}{16a^2a^2+19a^2a^2+17a^2a^2}$ = $\frac{11+13+15 }{16+19+17}$ = $\frac{39}{52}$ = $\frac{3}{4}$ Hence, the correct answer is $\frac{3}{4}$.
Question : Directions: If it was Thursday yesterday, then what was the day of the week 73 days ago from today?
Option 1: Tuesday
Option 2: Wednesday
Option 3: Sunday
Option 4: Thursday

Solution : Given: Yesterday was Thursday. So, today will be Friday.
Now, on dividing 73 by 7, we get 3 as a remainder. So, 3 days before Friday was Tuesday.
So, 73 days ago from today was Tuesday. Hence, the first option is correct.

Question : In a quarterly examination, a student secured 30% marks and failed by 12 marks. In the same examination, another student secured 40% marks and got 28 marks more than the minimum marks to pass. The maximum marks in the examination are:
Option 1: 300
Option 2: 500
Option 3: 700
Option 4: 400
Correct Answer: 400
Solution : Let the maximum marks be $x$. Passing marks = 30% of $x$ + 12 = 40% of $x$ – 28 ⇒ $(\frac{30}{100}×x)+12 $ = ($\frac{40}{100}×x) - 28$ ⇒ $(\frac{10}{100}×x) = 40$ So, the maximum marks, $x$ = 400 Hence, the correct answer is 400.
