In an amusement park, average number of visitors on Sunday is 560, on Monday is 210 and on remaining days of the week, average number of visitors is 210. Find the average number of visitors in a week.

210

260

250

280

Answer (Detailed Solution Below)

Option 2 : 260

Detailed Solution

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.

Answer 2

$Average \\ = \frac{M+T+W+ Thu+ Fr+ Sa+Su}{7}$

$= \frac{1200 + 1300 + 1400 + 1600 + 2500 + 3900}{7}$

$= \frac{11,900}{7}$

$= 1,700$
