Study the following table and answer the questions.

Number of machines (in thousands) sold by dealers A, B, C, D and E during six months of 2022.

The average of total no. of machines sold by dealers C in February, April and May exceeds the no. of machines sold by the dealer E in January by x.  The value of x lies between?

50 & 55

Total number of sale by C in Feb, April & May = 640 + 540 +625 = 1800

Average of machines sold by C in Feb., April and May = \(\frac{1800}{3}\) = 600

Machines sold by E in January = 548

ATQ,

x = 600 - 548 = 52

Hence x lies between 50 & 55
