Answers
Answer:
The Percentage is a relative value that indicates hundredth parts of any quantity. One percent (1%) represents the one hundredth, 2 percent (2%) represents two hundredths, 100% represents the whole, 200% twice the given quantity and so on… For example - 1 percent of 1000 mangoes is equal to 1/100 of 1000 or 10 mangoes.
Answer:
Percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

see the picture given:-
The square is divided into 100 smaller squares. As 25 of the smaller squares are unshaded, this indicates that 25 percent of the larger square is unshaded.
For example, 1 percent of 1,000 chickens equals 1/100 of 1,000, or 10 chickens; 20 percent of the quantity is 20/100 1,000, or 200. These relationships may be generalized as x = PT/100 where T is the total reference quantity chosen to indicate 100 percent, and x is the quantity equivalent to a given percentage P of T. Thus, in the example for 1 percent of 1,000 chickens, T is 1,000, P is 1, and x is found to be 10.
In many commonly occurring percentage problems, x and T are known, and the percentage of T that x represents is sought. For such cases it is convenient to use the equation P =
100x
/T
.
A frequent application of the second equation is in calculating percentage of profit or loss in business transactions. Suppose a retailer buys an item at a wholesale price T of $80 and sells it for $110 at a profit x of $30. From the equation, the percentage profit is 100 × 30/80, or 37.5 percent. Similarly, a merchant may put an item on sale, lowering the price T of $20 to $17; a reduction x of $3, or 15 percent.
