Question : Two stations A and B are 230 km apart on a straight line. One train starts from A at 4 a.m. and travels towards B at 40 km/hr. Another train starts from B at 5 a.m. and travels towards A at a speed of 55 km/hr. At what time will they meet?

Option 1: 10 a.m.

Option 2: 7 a.m.

Option 3: 6 a.m.

Option 4: 8 a.m.

Team Careers360 25th Jan, 2024

Correct Answer: 7 a.m.


Solution : Let the two trains meet $x$ hours after 4 a.m.
According to the question,
$40x+55(x-1)=230$
⇒ $95x=230+55$
⇒ $95x=285$
⇒ $x=\frac{285}{95}$
⇒ $x=3$
So, they will meet at (4 + 3) = 7 a.m.
Hence, the correct answer is 7 a.m.

Option 3: Rs. 1180

Option 4: Rs. 1250

Team Careers360 24th Jan, 2024

Correct Answer: Rs. 1260


Solution : Here CP denotes cost price and SP denotes selling price.
CP = SP$(\frac{100}{100-Loss\%})$
⇒ CP = 1140$(\frac{100}{100-5})$
⇒ CP = 1140$(\frac{100}{95})$
⇒ CP = Rs. 1200
Also, SP = CP$(\frac{100+Profit\%}{100})$
⇒ SP = 1200$(\frac{100+5}{100})$
⇒ SP = 1200$(\frac{105}{100})$
⇒ SP = Rs. 1260
Hence,
