A train 120m long passes a pole in 12 seconds.
here, distance travelled by train=length of train= 120m
time taken by train= 12 seconds
then speed of train=distance travelled by train/time taken by train
speed of train= 120m/12sec =10 m/sec
when train passes a 130 m long platform,
distance travelled by train= length of train + length of platform=120+130=250 m
time taken by train to pass 130 m long platform=distance covered by train / speed of train
time taken by the train= 250 / 10= 25 seconds

A tank has two pipes. Pipe A can fill the tank in 6 hours, and Pipe B can fill the tank in 8 hours. There is also a third pipe, Pipe C, which can empty the tank in 12 hours. ...

The point to be noted is that pipe A and B are used for filling the tank whereas pipe C empties the water.So we will take the time taken by pipe C in negative. It has been in the question that pipe A fills the tank in 6hours and pipe B fills the tank in 8 hour.Pipe C fills the tank in -12hours(SinceRead more
The point to be noted is that pipe A and B are used for filling the tank whereas pipe C empties the water.So we will take the time taken by pipe C in negative.
It has been in the question that pipe A fills the tank in 6hours and pipe B fills the tank in 8 hour.Pipe C fills the tank in -12hours(Since it empties the tank in 12 hours)
Tank A takes 6 hours So it will fill 1/6th of tank in 1 hour.Similarly Tank B will fill 1/8th of tank in 1 hour whereas Tank B will empty 1/12th of tank.
So after one hour:-
1/6+1/8-1/12=
(We will take L.C.M for 6,8,12 which is 24)
(4+3-2)/24=5/24.
So after one hour 5/24th of the tank will be filled. Since it is in the fraction 5/24, let us assume that capacity of tank is 24 litres and 5 litre is increased every hour.
So within 4 hours 20 litres will be filled into the tank.Time taken for the remaining 4 litres will be 4/5×60(we Multiply be 60 to convert into minutes).So it will take 48 minutes.
So the whole tank will get filled in 4 hour and 48 minutes or 60×4+48=288 minutes
The final answer is 4 hours and 48 minutes.

Hii shubham, I just solve this question and I pleased to share my answer with you…
So here’s the answer of your question:-
You can measure exactly 4 gallons of water using the 3-gallon jug and the 5-gallon jug by following these steps:
1. Fill the 5-gallon jug completely.
2. Pour water from the 5-gallon jug into the 3-gallon jug until the 3-gallon jug is full. This leaves you with 2 gallons in the 5-gallon jug.
3. Empty the 3-gallon jug.
4. Pour the 2 gallons from the 5 -gallon jug into the 3-gallon jug.
5. Fill the 5 -gallon jug completely again.
6. Pour water from the 5 -Gallon jug into the 3-gallon jug until the 3-gallon jug is full. Since the 3-gallon jug already has 2 gallons in it, you can only add 1 more gallon from the 5 -gallon jug.Now, you have exactly 4 gallons left in the 5-gallon jug.
Hope you understand this well and in case of any query I resolve it for you for better understanding.

Aptitude tests are commonly used in competitive exams for several reasons:
- Assessing Basic Skills : They measure fundamental skills such as numerical ability, logical reasoning, and verbal proficiency, which are essential for academic and professional fields.
- Standardization : These tests provide a standardized method to evaluate the abilities of all candidates, ensuring a fair comparison based on a common set of criteria.
- Predicting Success : Aptitude tests are designed to predict a candidate’s ability to succeed in future tasks, courses, or job roles. High scores often correlate with better performance in the relevant field.
- Identifying Potential : They help in identifying candidates with the potential to excel in specific areas, even if they lack prior knowledge or experience in those areas.
- Efficiency : Aptitude tests can quickly and efficiently screen large numbers of candidates, making the selection process more manageable.
- Eliminating Bias : By focusing on objective skills rather than subjective factors, aptitude tests help reduce biases that might arise from interviews or other subjective evaluation methods.
- Diagnostic Tool : These tests can diagnose strengths and weaknesses, helping candidates understand areas where they need improvement and aiding educators in tailoring their instruction accordingly.
