Percentages Understanding Percentages:
The word percent can be understood as follows: Per cent => for every 100.
So, when percentage is calculated for any value, it means that that you calculate the value for e 100 of the reference value. Why Percentage?
Percentage is a concept evolved so that there can be a uniform platform for comparison of vari things. (Since each value is taken to a common platform of 100.)
Eg: To compare three different students depending on the marks they scored we cannot directly
compare their marks until we know the maximum marks for which they took the test. But by calculating percentages they can directly be compared with one another. Before going deeper into the concept of percentage, let u have a look at some basics and tips calculations: You're Reading a Preview

Also, 2.125 = [8(2)+1]/8 = 17/8 (here the denominator is added to numerator twice) 3.125 = [8(3)+1]/8 = 25/8 and so on. Thus we can derive the fractions for decimals more than 1 by using those les than 1. We will see how use of fractions will reduce the time for calculations: Eg: What is 62.5% of 320? Soln: Value
= (5/8) X 320 (since 62.5% = 5/8) = 200.
Percentage Change:
A change can be of two types - an increase or a decrease. When a value is changed from initial value to a final value, % change = (Difference between initial and final value/initial value) X 100 Eg: If 20 changes to 40, what is
the % increase?
You're Reading a Preview Soln: % increase = (40-20)/20 X 100 = 100%. Unlock full access with a free trial.

Cost Price (CP):
The money that the trader puts in his business is called Cost Price. The price at w articles are bought is called Cost Price. In other words, Cost Price is nothing but the investment in the business. Selling Price (SP):
The price at which the articles are sold is called the Selling Price. The money that th gets from the business is called Selling Price. In other words, Selling Price is nothing but the returns from a business. Marked/Market/List Price (MP):
The price that a trader marks or lists his articles to is called the Marked Price. This is the only price known to the customer.

Ratios and Proportions What is a ratio?
A ratio is a representation of distribution of a value present among the persons present and is shown as follows:
If a total is divided among A, B and C such that A got 4 parts, B got 5 parts and C got 6 parts then it is represente as A:B:C = 4:5:6. So, 4:5:6 means that the total value is divided into 4+5+6 = 15 equal parts and then distributed as per the ratio. Example 1:
Divide Rs. 580 between A and B in the ratio of 14:15. Soln:
A:B = 14:15 => 580 is divided into 29 equal parts => each part = Rs. 20. So A's share = 14 parts = 14 x 20 = Rs. 280 B's share = 15 parts = Rs. 300. Example 2:
If A:B = 2:3 and B:C = 4:5 then find A:B:C.

Soln:
Let the numbers be a and b. A:B = 3:4 => A / B = 3 / 4. Also, (A+8) / (B+8) = 5 / 6. Solving we get, A=12 and B = 16 Example 6:
A garrison has provisions for 120 soldiers for 240 days. After 180 days 60 more soldiers will join the group. For more days will the provisions last? Soln:
Actually after 180 days, If 120 members are there provisions come for 60 more day s (since total 240 days) But now 180 members are th ere. So number of days= (120/180) X 60 = 40 days. Example 7:
