Answer 1

Step-by-step explanation:

The the total money spent by them is Rs 117

Solution:

Given that:

Nine persons went to a hotel for taking their meals

Eight of them spent rupees 12 each over there meals

Total amount spent by 8 of them is:

\rightarrow 12 \times 8 = 96→12×8=96

So total amount spent by 8 of them is Rs 96

Let "x" be the amount spent by all of them

The ninth spend rupees 8 more than the average expenditure of all the nine

amount spent by ninth person = 8 + x/9

According to given question,

amount spent by all of them = total amount spent by 8 of them + amount spent by ninth person

\begin{gathered}x = 96 + 8 + \frac{x}{9}\\\\x = \frac{864 + 72 + x}{9}\\\\x = 936\\\\x = 117\end{gathered}

x=96+8+

x=117

Thus the the total money spent by them is Rs 117
