Solution

The correct option is D The total number of students whose favourite colour is yellow and green colour is less than the number of students whose favourite colour is red.
(a) 120th of the total students equals 5. But 25 of the students voted for blue. Hence, this option is wrong.
(b) Green has a greater percentage on the pie chart than yellow and pink. So green cannot be the least favourite colour. Hence, this option is wrong.
(c) The number of students who voted for red is equivalent to 35. 35 is not twice of 20. Hence, this option is wrong.
(d) Total percentage of the students liking either green or yellow is 20%+14%=34%. This is less than the total percentage of students liking red, which is 35%. Hence, this option is right.
