Question

19 friends went to a restaurant for a combined weekend dinner party. 13 of them spent rs.79 each on their dinner and the rest spent rs.4 more than the average expenditure of all the 19.

Answer 1

Answer:

Rs. 1536.07

Step-by-step explanation:

Let average expenditure of 19 people be x

then,

19x = 13 × 79 + 6 × (x + 4)

or, 19x = 13 × 79 + 6x + 24

or, x = 80.84

So, total money spent

= 80.84 × 19

= Rs. 1536.07
