Some boys and girls of a school went to a trip. Girls are 8 more than boys, and so, boys are only 75% of number of girls. The budget of all girls is Rs. 96,000. The budget of boys is same as the budget of girls. There are 3 male and 5 female escorts for the students. But for compensating the expenditure of 2 male escorts they rejected 3 girls and for compensating the expenditure of 4 female escorts they rejected 6 boys. Find the ratio of expenditure of 2 male escorts to a female escort.
