. Nine men went to a hotel. Eight of them spent Rs. 3 for each over their meals and the ninth spent Rs. 2 more than the average expenditure of all the nine. What is the total money spent by them?

Rs. 29.25
Rs. 29.50
Rs. 29
Rs. 30

Solution:

Let the average expenditure of all the nine = Rs. x
Now amount spent by eight = Rs. 3 × 8 = Rs. 24
and total spent by the ninth = Rs. x + 2

⇒{26+x}/9=x

∴ Average amount spent by nine

{26+x}/9

Total amount spent by nine

= 24 + x + 2 = 26 + x

⇒ 9x = 26 + x
or, 8x = 26

⇒x=26/8=\Rs 3.25

Hence total money spent = Rs. (3.25 × 9) = Rs. 29.25
