• A. 30%
• B. 50%
• C. 45%
• D. 60%
• E. 25%

Answer 1

The correct option is B 50%

b. 50%

Combined expenses on bike and car in 2002 = .6, remains same in 2003. Bus forms 50% of his expenses in 2003. Thus bus expenses in 2003=combined expense on bike and car in 2003 = .6; also bus expense in 2002=.4 => % increase: (.6-.4)/.4 * 100 = 50%
