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
