Option 1: 0.13 metre

Option 2: 0.4 metre

Option 3: 0.3 metre

Option 4: 0.41 metre

Team Careers360 20th Jan, 2024

Correct Answer: 0.3 metre

Question : If $a+\frac{1}{a}=2$, then the value of $(a^{5}+\frac{1}{a^{5}})$ will be:

Option 1: 0

Option 2: 1

Option 3: 3

Option 4: 2

Team Careers360 16th Jan, 2024

Correct Answer: 2


Solution : Given: $a+\frac{1}{a} = 2$
If we take $a=1$, then LHS = $1+\frac{1}{1}=2$ = RHS
So, $a=1$ satisfies the equation.
Now, $a^5+\frac{1}{a^5}=1^5+\frac{1}{1^5}=2$
Hence, the correct answer is 2.

Question : A policeman saw a thief from a distance of 450 m. When the policeman started chasing him, the thief also started running. The ratio of speeds of the thief to the policeman is 7 : 8. After running how much distance (in km) can the policeman catch the thief?

Option 1: 3.75

Option 2: 3.4

Option 3: 3.6

Option 4: 3.15

Team Careers360 15th Jan, 2024

⇒ Relative speed $= 8a - 7a=a$ m/sec
Now,
Time taken to catch the thief $= \frac{450}{a}$ sec
⇒ Distance travelled by the policeman $= (\frac{450}{a}) × 8a=3600$ m or
