A frog is at the bottom of the well which is 20 meters deep. - with Answer

A frog is at the bottom of the well which is 20 meters deep. Everyday the frog jumps 5 meters upwards and fall 4 meters down. How many days it will take for the frog to reach the top?

Solution:

First day it jumps 5 meters and falls 4 meters. Now it will be at a height of 1 meter.

Second day, it jumps to 6 meters and falls back to 2 meters.

Third day it jumps to 7 meters and falls back to 3 meters.

          .......

Fifteenth day it jumps to 19 meters and falls back to 15 meters.

Finally, sixteenth day it jumps to 20 meters, but now the frog has reached the top of the well.

So the Frog reaches the top of the well as the sixteenth day.

A man driving his bike at 24 kmph reaches his office 5 minutes late... - with answer

A man driving his bike at 24 kmph reaches his office 5 minutes late. Had he driven 25% faster on an average he would have reached 4 minutes earlier than the scheduled time. How far is his office?

Answer: 18 km

Let x km be the distance between his house and office.
While travelling at 24kmph, he would take $\frac{x}{24}$ hours.
While travelling at 25% faster speed,
i.e. $24+25\%\text{of}24=24\times \left(\frac{1}{4}\right)=30$ kmph, he would take $\frac{x}{30}$ hours.
Now as per the problem, time difference = 5 min late + 4 min early = 9 min
⇒ $\frac{x}{24}-\frac{x}{30}=9\text{min}$
⇒ $x=$ 18 km

The sum of three numbers is 98. The ratio of the first to the second ... with Answer

The sum of three numbers is 98. The ratio of the first to the second is , and the ratio of the second to the third is . The second number is..?

Answer:

Let the second number be x.
Therefore, first number 2/3x  and the third number = 8/5x
Therefore, 2/3x+x+8/5x=98
Solving the above equation we get answer is: 30

There are 3 cars moving at speeds in the ratio of. If the fastest car covers 10 km... - with answer

There are 3 cars moving at speeds in the ratio of. If the fastest car covers 10 km more than the car with medium speed in 30 minutes, then the speed of the slowest car in kmph is...?

Answer:

Let the speeds of the three cars be 1.5y kmph, 2.5y kmph, and 3y kmph.

The fastest car, then, covers 3y/2 km in 30 minutes.

Therefore, the speed of the slowest car is (1.5 × 40) = 60 kmph.

Two friends A and B run around a circular track ... - with answer

Two friends A and B run around a circular track of length 510 meters, starting from the same point, simultaneously and in the same direction. A who runs faster laps B in the middle of the 5th round. If A and B were to run a 3 km race long race, how much start, in terms of distance, should A give B so that they finish the race in a dead heat?

Answer:  666.67 metres.

A and B run around a circular track. A laps B in the middle of the $5^{th}$ lap. i.e. when A has run four and a half laps he has covered a distance which is 1 lap greater than that covered by B's.

Therefore, when A runs $\frac{9}{2}$ laps, B runs $\frac{7}{2}$ laps.

This is same as saying when A runs 9 laps, B runs 7 laps.

i.e in a race that is 9 laps long, A can give B a start of 2 laps.

So, if the race is of 3000 metres long, then A can give B a start of  $\left(\frac{2}{9}\right)\times 3000=$ 666.67 metres.
