Answer: Option C
Solution(By Examveda Team)
Let the average expenditure of all the nine be Rs. X Then, 12 × 8 + (X + 8) = 9X ∴ X = 13 Total money spent = 9X= Rs. (9 × 13)
= Rs. 117

Its took 9th person as x, so wrong!
Right answer (12x8)+(12+8)
=116
I think answer is 116
why to take ninth person as x..?
8 of them spent 12 rs each but 9th person spent 8rs more than others so we can take it as 12+8 right..?
