5. In a retail market, fruit vendors were selling mangoes kept in packing boxes. These boxes contained varying number mangoes. The following was the distribution of mangoes according to the number of boxes.

Find the mean number of mangoes kept in a packing box. Which method of finding the mean did you choose?

Ans. Since value of number of mangoes and number of boxes are large numerically. So we use step-deviation method.

From given data, Assume mean  = 57, Width of the class  = 3

  =  (approx.)

Using formula, Mean  = 57 + 3 (0.0625) = 57 + 0.1875 = 57.1875 = 57.19 (approx.)

Hence mean number of mangoes kept in a packing box is 57.19.
