These SUPER SPECIAL TRICKS helps in getting
CUTOFF score in exams. Use these tricks to solve SIMPLE INTEREST BASED
QUESTIONS in any of the competitive exam.
SUPER SPECIAL TRICKS to solve SIMPLE INTEREST questions Top are
described as follows:
1. Amount
= Principle + Simple Interest (SI)
2. Take
Principle = Rs. 100/ always.
3. Count
SIMPLE INTESTEST (SI) = Rate x Time
Where Rate in %age and Time in Years.
Use SI Table for Rate & Year
(On the basis of Principle amount =
100).
.

4. If
successive increase in rate of interest is given for two different sums for
same period of time say increase in rate of interest are X% and Y% for Z years.
Then the average rate of interest on these two different sum = X + Y +
(X.Y)/100 (for clarity see examples).
5. If
any sum becomes X times in any Y years at any simple rate of interest , then
the same times will be continue for next same no. of years (for clarity see
examples).
6. If
any sum becomes X times in any Y times at any SI, then percentage rate of
interest will be calculated first by doing [(X1)] and then multiply this value
to Y*100.
7. If
any sum becomes X times in any Y years at any SI.
Y Years
Let Sum 1X (times)
? Years
1Z (times)
So the time required to obtain the sum
Z times first do (Z1) and then (X1)] then multiply these two values with Y.
8. If
any sum becomes X times at Y% rate of interest (RI).
Y% RI
Let sum 1X
(times)
Then SI per year will be calculated by
first do (X1) then divided this value by/Y and last multiply by 100 to get the
RI in %age.
Some Examples of Math Short
Tricks for IBPS / SBI/ SSC CHSL Exam 201516
Question 1:
If a sum gets double itself at a rate
of 15% per year for a certain period of time. Calculate the SI.
Solution: Using SUPER SPECIAL TRICKS:
15% RI
Let sum
12 (times)
Then SI = [(21)/15]*100 = 20/3 = 6.67
Similarly use these SUPER SPECIAL
TRICKS to solve such Simple Interest questions.
