Profit and Loss Formulas and Tips
Profit and loss is the one of major question section in Competitive exams. These formulas will be helpful for your upcoming Exams like PSC, SSC, IBPS and Other Competitive Exams.
- Cost Price(CP) : The Price at which a particular item purchased, is called its Cost Price.
- Selling Price (SP): The price at which a particular item is sold, called its Selling Price.
- Profit: If Selling Price of an item is more than Cost Price , then vendor is said to have a Profit.
- Loss: if Selling Price of an item is less than Cost Price, the vendor said to have a Loss.
Formulas
- Profit = SP – CP
- Profit % = Profit/(CP)×100
- SP = ((100+Profit% )/100)×CP
- CP = (100/(100+Profit%))×SP
- Loss = CP – SP
- Loss% = Loss/(CP)×100
- SP = ((100-loss%)/100)×CP
- CP = (100/(100-loss%))×SP
Examples:
1. The cost price of 40 apples is the same as the selling price of 25 apples. Find the gain percent.
Answer:
=(40-25)/25×100
=15/25×100=60%.
2. A Table was purchased for Rs. 470 and sold at a profit of 10%. Find the selling price.
Answer:
=(100+10)/100 X 470
=517.

Permutation and combination related questions are common in PSC and Bank exams.
Before going to Combinations and Permutations, first lean about factorial. .
If n is a positive integer then, factorial of n is denoted as n! . .
4! = (1 x 2 x 3 x 4 ) = 24.
Permutations are for lists of items, whose order matters and combinations are for group of items where order doesn’t matter. in other words, .
When the order of items doesn\\\'t matter, it is called as Combination.
When the order of items does matter it is called as Permutation.
The number of permutations of n objects taken r at a time is determined by using this formula:.
C(n,r)=n!/((n−r)!r!) .
Combination : Picking a team of 3 people from a football coaching group of 10. C(10,3) = 10!(3!(10−3)!) = 120. ....
BODMAS is an acronym and it stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. .
This explains the order of operations to solve an expression. According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve/simplify the bracket followed by of (powers and roots etc.), then division , multiplication , addition and subtraction from left to right. .
Example :.
7 + (6 × 52 + 3) = 7 + (6 × 25 + 3).
7 + (150 + 3).
7 + (153).
7 + 153 .
Ans: 160. .
