Question : Two trains 320 m and 205 m in length are running towards each other on parallel lines. One train runs at the rate of 70 kmph and the other train runs at the rate of 56 kmph. Find the time they will take to cross each other (in seconds).

Option 1: 10

Option 2: 20

Option 3: 12

Option 4: 15

Team Careers360 24th Jan, 2024

Correct Answer: 15


Solution : Let $s$ be the relative speed of the trains, $d{_1}$​ be the length of the first train, and $d{_2}$​ be the length of the second train.
⇒ $s=70+56=126\mathrm{\ km/hr}=126\times \frac{5}{18}\mathrm{\ m/s}=35\mathrm{\ m/s}$
Time $=\frac{d{_1}+d{_2}}{s}=\frac{320+205}{35}=\frac{525}{35}=15$ seconds
Hence, the correct answer is 15.

Question : A mixture of 70 litres of wine and water contains 10% of water. How much water must be added to make the water $12 \frac{1}{2}\%$ of the resulting mixture?

Option 1: 5 litres

Question : If $(x+\frac{1}{x})^2=3$, then the value of $x^{206}+x^{200}+x^{90}+x^{84}+x^{18}+x^{12}+x^6+1$ is:

Option 1: $0$

Option 2: $1$

Option 3: $84$

Option 4: $206$

Team Careers360 24th Jan, 2024

Correct Answer: $0$


Solution : Given: $(x+\frac{1}{x})^2=3$
We know that the algebraic identity is $(x+\frac{1}{x})^3=x^3+\frac{1}{x^3}+3(x+\frac{1}{x})$.
$(x+\frac{1}{x})^2=3$
By taking the square root on both sides of the above equation, we get,
$(x+\frac{1}{x})=\sqrt3$
By taking the cube on both sides of the above equation, we get,
$(x+\frac{1}{x})^3=(\sqrt3)^3$
$x^3+\frac{1}{x^3}+3(x+\frac{1}{x})=3\sqrt3$
Substitute the value of

Option 1: 1

Team Careers360 23rd Jan, 2024

There is a missing indefinite article "a" before "message" to make the sentence grammatically correct, hence the article "a" should be used before a singular countable noun.

Therefore, the correct sentence should be: "He had already
