1)

What percent of the average sales of branches B1, B2 and B3 in 2001 is the average sales of branches B1, B3 and B6 in 2000?


A) 45

B) 82.5

C) 90.6

D) 87.5

Answer:

Option D

Explanation:

Total sales (in thousands numbers) of branches B1, B3 and B6 in 2000

= 80+95+70=245

Average sales (in thousands number) of branches B1, B3 and B6 in 2000

= $\frac{245}{3}$

Total sales (in thousands number) of branches B1, B2 and B3 in 2001

= 105 + 65 + 110 = 280

Average sales (in thousands number) of branches B1, B2 and B3 in 2001

= $\frac{280}{3}$

So, required percentage = $\left(\frac{245}{280}\times100\right)$ % = 87.5%
