4. 150

Answer 1

Correct Answer - Option 1 : \(149\frac{2}{7}\)

Given

A library has an average of 265 visitors on sunday and 130 visitors on the other days. 

Concept used

Average

Calculation

We have 7 days in a week

Number of visitors on sunday = 265

135 visitors on other days = 130 × 6 = 780

Sum = 265 + 780

Sum = 1045

Average = \(\frac{{1045}}{7}\)

Average = \(149\frac{2}{7}\)
