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.

Combinations and Permutations

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. ....

9,312, for instance, is divisible by 4 since its last 2 digits are 12. And 12 is divisible by 4.
What is the divisibility by 5 rule?.
A number is divisible by 5 if its last digit is a 0 or 5.
What is the divisibility by 6 rule?.
