M = per brand average number of watches sold from Showroom 1
What is the ratio of the number of watches of Brand 3 sold from Showroom 2 to M?
Answer & explanation
Correct answer: option 4
⇒ M = per brand average number of watches sold from Showroom 1
= \(\frac{60+55+75+48+52 }{5}\)
= \(\frac{ 290 }{5}\)
= 58
⇒ Watches of brand 3 sold from showroom 2 : M
⇒ 50 : 58
⇒ 25 : 29
