Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 40.9%
Calculations:
Total number of blue pens = 42 + 48 + 52 + 64 + 44 + 60 = 310
Total number of green pens = 27 + 33 + 39 + 51 + 42 + 28 = 220
Required difference = 310 - 220 = 90
Required percentage = (90/220) × 100 = 40.9%
