Question

$23$ people had lunch in a hotel and the rate per lunch is the same for all. If it costs $Rs.3105$ in total, how much will it cost for $60$ people to have lunch in the same hotel at the same rate?

Answer 1

Lunch for $23$ people $=3105$

Lunch for $1$ person $=\frac{3105}{23}$

$=Rs135$

Now

Lunch for $60$ people $=135\times 60$

$=Rs8100$
