Option 1: 4025

Option 2: 4500

Option 3: 5000

Option 4: 4000

Team Careers360 27th Jan, 2024

Correct Answer: 4025


Solution : Number of workers in Category B was 1500 in the year 1995.
It is given that 15% of the workers are in Category B.
So, 15% of the workers are in Category B = 1500
$\therefore$ 25% of workers in Category D $= \frac{1500}{15}×25=2500$
In 1996, the number of workers in Category B increased by 10%.
So, workers in Category B in 1996 $= \frac{110}{100}×1500=1650$
In 1996, the number of workers in Category D decreased by 5% in 1996.
So, workers in Category D in 1996 $= \frac{95}{100}×2500=2375$
$\therefore$ Total workers in Category B and D in 1996 = 1650 + 2375 = 4025
Hence, the correct answer is 4025.

Question : If $a^{2}+b^{2}+c^{2}=ab+bc+ca,$ then the value of $\frac{a+c}{b}$ is:

Option 1: 3

Option 2: 2

Option 3: 0

Option 4: 1

Team Careers360 26th Jan, 2024

Correct Answer: 2


Solution : Given: $a^{2}+b^{2}+c^{2}=ab+bc+ca$
⇒ $a^{2}+b^{2}+c^{2}-ab-bc-ca=0$
⇒ $\frac{1}{2}\left[(a-b)^{2}+(b-c)^{2}+(c-a)^{2}\right]=0$
⇒ $(a-b)^{2}+(b-c)^{2}+(c-a)^{2}=0$
The square of any real number is always non-negative.
Therefore, we have:
$(a-b)^{2}=0 \Rightarrow a=b$
$(b-c)^{2}=0 \Rightarrow b=c$
$(c-a)^{2}=0 \Rightarrow c=a$
Thus, we have $a=b=c$. Now, we can calculate $\frac{a+c}{b}$ as follows:
$\frac{a+c}{b}=\frac{a+a}{a}=2$
Hence, the correct answer is 2.
