Correct Answer: 8 : 25
Solution :
$J_1$ = The average sale of bikes of companies P, Q, and R
= $\frac{200+100+500}{3}$ = $\frac{800}{3}$
$J_2$ = The average sale of cars of companies R, S, and T
= $\frac{700+1000+800}{3}$ = $\frac{2500}{3}$
So, $J_1:J_2$ = $\frac{800}{3}:\frac{2500}{3}$ = 8 : 25
Hence, the correct answer is 8 : 25.
