Question

A man's average of daily income from Sunday to Thursday is Rs 75 . If he earns Rs 93 on Friday , find his average income of 6 days

Answer 1

78

Explanation:

Average income from Sunday to Thursday = Rs 75.

There are 5 days .

So average = sum / 5

= sum = 5 average

= sum = 5 × 75

= sum = 375

He earns Rs 93 on Friday .

So adding this sum = Rs 375 + 93

= Rs 468

Average = sum / number of terms

= Average = 468/6

= Average = 78

Hence the average is 78 .
