A certain party consists of four different group of people - 30 students, 35 politicians, 20 actors and 27 leaders. On a particular function day, the total cost spent on party members was Rs.9000. It was found that 6 students spent as much as 7 politicians, 15 politicians spent as much as 12 actors and 10 actors spent as much as 9 leaders. How much did students spent?
Select the correct option:
A) 2377.55  B) 2477.55  C) 2577.55  D) 2677.55  E) 2777.55
as question says,   30s+35p=20a+27L =9000 say eqn 1   6s=7p , 15p=12a , 10a=9L   or   6s=7p , 7p=(12*7)/15 a =(28/5)a , (28/5)a= (28/50)*9L   OR   6s=7p=(28/5)a=(252/50)L = K   now   s=(k/6), p= (k/7) , a=(.1785k) , L=(.1984k)   put these value in eqn one you will got value of k is 475.511   now 6s=k   hence s=k/6=79.25   there are 30 students hence 79.25*30=2377.55   2377.55NSWER:2377.55
