Option 2: 0.15 and 0.25

Option 3: 0.25 and 0.35

Option 4: 0.05 and 0.15

Team Careers360 23rd Jan, 2024

Correct Answer: 0.25 and 0.35


Solution : Given:
$\frac{0.325 \times 0.325+0.175 \times 0.175-25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}$
$=\frac{0.325 \times 0.325+0.175 \times 0.175-2 \times 0.325\times0.175}{(0.325)^2- (0.175)^2 }$
$=\frac{(0.325 -0.175)^2}{(0.325+0.175)(0.325-0.175) }$
$=\frac{(0.325 -0.175)}{(0.325+0.175) }$
$=0.3$
Hence, the correct answer is 0.25 and 0.35.

Question : The speed of the current is 5 km/h. A motorboat goes 10 km upstream and back again to the starting point in 50 minutes. The speed (in km/h) of the motorboat in still water is:

Option 1: 20

Option 2: 26

Option 3: 25

Option 4: 28

Team Careers360 14th Jan, 2024

Correct Answer: 25


Solution : Let the speed of the boat be $x$ km/h.
Given: The speed of current = 5 km/h
Therefore, upstream speed of boat = $(x-5)$ km/h
Downstream speed of the boat = $(x + 5)$ km/h
According to the question,
$ \frac{10}{x-5}+\frac{10}{x+5}=\frac{50}{60} $
⇒ $10 \left(\frac{x+5+x-5}{x^{2}-25}\right)=\frac{5}{6}$

Question : In a cricket match, there are three types of tickets say A, B, and C each costing Rs. 1000, Rs. 500, and Rs. 200 respectively. The ratio of the tickets sold in categories A, B, and C is $3:2:5$. If the total collection from selling the tickets is Rs. 2.5 crores. Find the total number of tickets sold.

Option 1: 5000

Option 2: 4800

Option 3: 50000

Option 4: 52000

Team Careers360 25th Jan, 2024

Correct Answer: 50000


Solution : Let the number of tickets be $3n, 2n,$ and $5n$.
According to the question,
$(3n×1000)+(2n×500)+(5n×200) = 25000000$
⇒ $3000n+1000n+1000n = 25000000$
⇒ $5000n = 25000000$
⇒ $n = \frac{25000000}{5000}$
$\therefore n= 5000$
So, total number of tickets $=(3n+2n+5n) = 10n= (10 × 5000) = 50000$
