It’s Given Samsung and Motorola companies together can manufacture 32 Cell phones in 4 days

∴ both can manufacture (32/4) = 8 Cell phones in 1 day.

⇒ Amount of cell phones manufactured in 8 days = 64 cell phones

Total cell phones manufactured = 100

Amount left = 100 – 64 = 36

⇒ Samsung took 12 days to manufacture 36

∴ It manufactured 3 Cell phones in 1 day.

Since in 1 day both can manufacture 8 Cell phones and out of which Samsung can manufacture 3 per day.

⇒ Motorola can manufacture 8 – 3 = 5 cell phones/day.

To manufacture 15 set Motorola will need 15/5 = 3 days.
