Question:Nine persons went to a hotel for taking their meals. Eight of them spent Rs. 12 each on their meals and the ninth spent Rs 8 more than the average expenditure of all the nine. What was the total money spent by them?
Answer Let the expenditure be x. Then, average =`x/9` `:.` `8 xx 12 +(x/9 + 8)` = x or `x - (x/9)` = 104. or `(8x)/9` = 104 or x =`((104 xx 9)/8)` = 117
