D. 36
Answer Explanation
Determine the number of blue and yellow gumballs as follows:
Percent of blue gumballs=100%-(20%+30%+5%+10%) =100%-65%=35%
Number of blue gumballs35% of 120=0.55*120 = 42 blue gumballs [35%=35/100=0.35]
Number of yellow gumballs=5% of 120=0.05*120 = 6 yellow gumballs [5%=5/100=0.05]
Difference between the number of blue and yellow gumballs=42-6= 36 balls
Therefore, there are 36 more blue gumballs than yellow gumballs.
