Wholesale price index number for the year 2014 = 177.6 and

Wholesale price index number for the year 2015 = 181.2

Rate of inflation =

$=\frac{(Wholesale\, price\, index \, number\, for\, the\, year \,2015)-( Wholesale \,price\, index\, number\, for\,the\, year\, 2014)}{Wholesale\, price\, index\, number \,for\, the\, year\, 2014} \times 100$

$=\frac{181.2-177.6}{177.6} \times 100$

$=\frac{3.6}{177.6} \times 100$

$0.0203\,\times 100$

= 2.03 %
