Given:
Total number of friends = 6
Amount contributed = Rs. 150
Contribution by sixth person = Rs. 40
To Find:
The total bill value
Solution:
Let the money spent by sixth person be = Rs. x
Now five of them pay Rs. 150 each
Total money spent = 150 × 5 + x
= 750 + x
Now,
The 6th person spent Rs. 40 more than the average expenditure of all six.
Therefore -
x = Average of all six + 40
x = Total Amount/ Total people + 40
x = 750 + x/6 + 40
x = 750 +x + 240/6
6x = 990 + x
5x = 990
x = 990/5
198
Total money spent = 750 + 198
= 948
Answer: The total bill value is Rs. 948.
