Option 2 : 260

**Given**

Number of visitors on Sunday = 560

Number of visitors on Monday = 210

The average number of visitors from Tuesday to Saturday = 210

**Formula used**

Average = (sum of all observation)/Number of observation

**Calculation**

Number of visitors from Tuesday to Saturday = 210 × 5

⇒1050

Average number of visitors in a week = (560 + 210 + 1050)/7

⇒1820/7

⇒260

**∴ 260 is the average number of visitors on a week.**
