Answer: (C) 150 to 170
Step-by-step explanation:
Total No. of girls = 300
No. of girls who chose drama = 170
No. of girls who chose singing = 240
No. of girls who chose nothing = At least 40
Taking the minimum number 40
No. of girls who chose at least one activity = 260
Therefore, Minimum No. of girls who chose both the activities =
170 + 240 - 260 = 150
The only range which satisfies this range is C.
