The owner of the rice store asked the boy to go to the hotel to pick up 7 bottles of white wine and 15 bottles of red wine.

Explanation: Suppose x times of wine are taken.

15x 53=3 (7x 3) 2

15x 53=21x 9 2

15x 53=21x 11

21x- 15x=53-11

6x=42

x=7

Red wine: 15×7 53=158 (bottle) White wine: 7×7 3= 52 (bottles)

The hotel originally had more red wine than white wine: 158-52=106 (bottles)
