According to the meaning of the question, the turnover in the first half of the year was 2.3 million yuan, and the turnover in the second half accounted for 54% of the whole year.

Then the turnover in the first half of the year accounts for 1-54%=46% of the whole year.

Corresponding to the turnover in the first half of the year, we assume that the annual turnover is X million yuan.

Then 46%X=230, X=500,

Therefore, the turnover of Gu Feng Tourism Company in the first half of last year was 2.3 million yuan, the turnover in the second half accounted for 54% of the whole year, and the turnover last year was 5 million yuan.

Extended data:

I. Calculation of operating income:

Commonly used turnover rate formulas are:

Turnover/number of transactions = average transaction unit price

Turnover/sales volume = average unit price of products

The calculation formula for the year-on-year growth rate of operating income is:

Year-on-year growth rate of operating income = (current operating income-previous operating income)/previous operating income × 100%

The current operating income can be calculated monthly, quarterly and annually according to the needs of users, and it can also be from the beginning of the fiscal year to the end of the accounting statements, such as 2011to 2011September 30th. In addition, it can also be annualized data used by analysts, such as 20 1.

The operating income of the previous period refers to the operating income of the previous year corresponding to the operating income of the current period.

Second, the percentage of reciprocity.

1, conversion between percentages and decimals

(1) Decimal system: Delete the percent sign and move the decimal point to the left by two places. For example, 75% can be converted into 0.75.

(2) Decimal percentage: add a percent sign and move the decimal point to the right by two places. For example, 0.62 can be converted into 62%

Description:100% =1.00 =1.

2. Conversion between percentages and fractions

(1) Percentalized fraction: Write the percentage as a fraction with the denominator of 100, and then reduce the differential.

Note: When the percentage of molecules is decimal, the molecules should be converted into integers first.

For example:

(2) Percentage of scores:

The numerator of (1) is divided by the denominator to become a decimal and then a percentage.

For example:

② Multiply the numerator denominator by a number at the same time to make the denominator 100, and then turn the denominator into a percentage sign.

For example:
