Though petitioner’s household personal property was valued for tax purposes by Pitt County under the percentage method of appraisal at $3,660 but was valued at $4,100 under an on-site appraisal made at his request, he does not contend that this property was appraised in excess of its “true value in money,” the appraisal standard required by G.S. 105-283. Rather, he attacks the percentage method of appraisal on the following grounds: (1) that the method violates Article V, Sec. 2 (2) of the North Carolina Constitution because it results in an unauthorized classification of property by Pitt County and the taxation of a class of property by a non-uniform rule; and (2) that the method violates G.S. 105-283 because it does not appraise household personal property at its true value in money, and violates G.S. 105-317.1 (a) because the assessors do not consider the factors therein listed in appraising this property.
 We consider first the standing of the petitioner to attack broadly the percentage method of appraisal of household personal property in Pitt County. G.S. 105-322(g) (2) provides:
“On request, the board of equalization and review shall hear any taxpayer who owns or controls property taxable in the county with respect to the listing or appraisal of his property or the property of others.” (Emphasis added.)
In King v. Baldwin, 276 N.C. 316, 172 S.E. 2d 12 (1970), it was held that statutes (now G.S. 105-322 (g) (2) and G.S. 105-324 (b)) of the Machinery Act provide adequate means whereby the taxpayer may contest not only the valuation of his own property but also the entire tax list or assessment valuation. And see In Re Valuation, 282 N.C. 71, 191 S.E. 2d 692 (1972) ; In re King, 281 N.C. 533, 189 S.E. 2d 158 (1972).
We hold that petitioner has the right in this proceeding to attack the percentage method of appraisal of household property used in and by Pitt County.
“Classification. Only the General Assembly shall have the power to classify property for taxation, which power shall be exercised only on a State-wide basis. No class shall be taxed except by a uniform rule, and every classification shall be made by general law uniformly applicable in every county, city and town, and other local taxing unit of the State. The General Assembly’s power to classify property shall not be delegated.”
The fallacy in this position is that the percentage method of appraising household property is not a classification of this property separate and apart from other personal property, but is a method or formula for determining the “true value in money” of this kind of property. Appraising each item of household property would be an impossible task. There is some reasonable relationship between the value of a home and the value of the household property within. The percentage method is thus a reasonable one in accomplishing the object of determining the market value of household property. And petitioner’s evidence that under the percentage method his household property was valued at $3,660 but was valued at $4,100 by the “on-site” appraisal does not establish that the percentage method of valuation results in household property being valued at less than market value in Pitt County, or that the method is arbitrary per se. The taxing authority of Pitt County concedes that the percentage method resulted in the household property of some taxpayers being appraised above and some below market value. The average percentage method value and the average market value of all household property in the county is approximately the same, and there is a reasonable relationship between the two among all taxpayers. We find no violation of this constitutional provision.
 Too, the petitioner contends that the percentage method of valuation violates G.S. 105-283 and G.S. 105-317.1. In substance these two statutes provide that all property shall be appraised at market value, and' that all the various factors which enter into the market value of property are to be considered by the assessors in determining this market value for tax purposes. The difficulty of estimating the value of household property makes it impossible to appraise each item of such *472property precisely at actual market value, and in construing the applicable provisions of the Machinery Act, we must assume that the legislature recognized this impossibility and did not intend an unjust or absurd result. King v. Baldwin, supra.
Equality of appraisal, with resulting equity in taxation, is fundamental in the Machinery Act. There may be reasonable variations from market value in appraisals of property for tax purposes if these variations are uniform. A uniform and dependable method of property appraisal which gives effect to the various factors that influence the market value of property and results in equitable taxation does not violate the appraisal provisions of the Machinery Act. See In re Block Co., 270 N.C. 765, 155 S.E. 2d 263 (1967), and In re Trucking Co., 281 N.C. 375, 189 S.E. 2d 194 (1972), which upheld the method of appraising motor vehicles by the “Blue Book” if the method was not used arbitrarily in ascertaining fair market value.
 Petitioner points out that G.S. 105-285 requires that the value of personal property be determined annually, but G.S. 105-285 (d) and G.S. 105-286 require that the value of real property be determined every eight years; therefore, the percentage method of appraisal of household property results in the appraisal only every eight years in violation of G.S. 105-285. It is noted that the taxing authority in Pitt County made a study in 1968 which showed the value of household property to be 14% of the value of the taxpayers’ residence and lot, and that four years later in 1972 a new study was made which determines the value of household property to be 10% of the value of such realty. Under these circumstances we must assume, nothing else appearing, that the taxing authority of Pitt County found no significant change in the household and home realty ratio during the period from 1968 to 1972 and determined annually that the percentage method established as a result of the 1968 study was a reasonably accurate valuation of household property in the county during this period. Ad valorem tax assessments are presumed to be correct, and when such assessments are challenged, the burden of proof is on the taxpayer to show that the assessment was erroneous. In re Appeal of Amp, Inc., 287 N.C. 547, 215 S.E. 2d 752 (1975).
It would be meaningless to construe literally the applicable appraisal statutes of the Machinery Act. These statutes must be interpreted in the light of tax history and legislative purpose in formulating laws to guide local authority in the difficult *473and complex problem of appraising property for tax purposes. We find in this case that Pitt County has adopted an appraisal method for household property which is equitable and with reasonable uniformity and accuracy reflects market value, and in so doing does not violate the applicable appraisal statutes.
The evidence and the findings fully support the conclusions of the State Board of Assessment and the judgment entered in Superior Court.
The judgment is
