By what percent is the total number of books sold by store B less than that sold by store D in all the months taken together ?

Solution

Number of books sold by store B in all the months taken together

= 161 + 123 + 154 + 272 + 107 = 817

Number of books sold by store D in all the months taken together

= 255 + 176 + 98 + 284 + 167 = 980

=> Required % = $$\frac{980 - 817}{980} \times 100$$

= 16.6 % $$\approx$$ 16 %
