Let us assume E was the expenditure in 1994.
As we can see in the graph given that,
Profit = 15 % ,
Income in 1994 = 160
Then according to question,
E + E x 15 % = 160
E + E x 15 /100 = 160
(100E + E x 15 ) /100 = 160
115E / 100 = 160
115E = 160 x 100
E = 160 x 100 / 115
E = 139.13
Expenditure in 1994 E = 139.13 ? 140 Million
Bank A has given the maximum loan in 2007
Number of students studying in school B in 1994 = 950 + (350 ? 150) + (225 ? 115) + (185 ? 110) + (200 ? 90) = 950 + 200 + 110 + 75 + 110 = 1445.
Expenditure on the game of Football = 15% of total amount spent
Expenditure on the game of Hockey = 15% of total amount spent
Therefore, the ratio of the expenditure on the two game = 1 : 1
