To understand the tips of percentages consider the following cases:
To understand the tips of Profit loss consider the following terms
In these types of questions, some members of the series are given and you have to find the missing one.
For your reference some series are given and you have to keep these series in mind to solve these problems.
Tip 1: While solving these problems, draw the diagram as shown in adjacent image.
Consider right hand side as East, Left Side West. Top North and bottom South.
Diagonal directions
(NE , SE, NW, SW) are also mentioned as shown.
Tip 2: You will always start your question with starting point origin that is S. Means consider yourself sitting at point S.
Tip 3: Rotation of 180 degree in clockwise or anti-clockwise direction means you are pointing in opposite direction. It means if your present face is towards east and now you rotate yourself through an angle of 180 degree, either clockwise or anti-clockwise. After Rotation you will face towards West.
Tip 4: Rotation of 45 degree in clockwise or anti-clockwise direction means you are facing in diagonal directions. It means if your present face is towards east and now you rotate yourself through an angle of 45 degree clockwise. After Rotation you will face towards South East (SE)
Tip 5: Rotation of 90 degree in clockwise or anti-clockwise direction means you are turning towards right side or left side. It means if your face is towards East and now you rotate left side, It means you rotate 90 degree towards anti-clockwise direction and now your face will be towards North.
Tip 6:
Using Pythagoras theorem
h2 = p2+ b2
Here p = perpendicular, b = base and h = hypotenuse.
If certain sum of money becomes N times in T years, Then rate of interest is given by as shown.
For example, If certain sum of money becomes 4 times in 15 years at certain Simple rate of interest, then rate of interest is given by:
If certain sum of money becomes N times in T years at rate of interest R% , Then Time in years is given by as shown.
For example, If certain sum of money becomes 8 times at Simple rate of interest 28%, then Time is given by:
