• B. 0.8
• C. 1.2
• D. 0.7

Answer 1

The correct option is A

0.9

Average bill amount spent by customer in a group =

Total bill amount spent by customers in a group =

$=RS.\frac{\left[\right(80\ast 5.20)+(50\ast 4.30)+(28\ast 4)+(30\ast 3.9)+(100\ast 5.5)+(72\ast 6\left)\right]}{[80+50+28+30+100+72]}$

= Rs 5.12

Total bill amount spent by single customers =

$=RS.\frac{[6\ast 210)+(4.8\ast 120)+(4\ast 50)+(4.2\ast 60)+(5.8\ast 180)+(6.1\ast 130)]}{[210+120+50+60+180+130]}$

= Rs.5.50

$Ratio=\frac{5.12}{5.50}=0.9\left(approx\right)$
