Answer: Option A
Explanation:
Boys not enrolled in French at present = 31
2 of these enrol along with 19 new boys
-> Boys now not enrolled in French = 31-2 = 29
Boys now enrolled in French = 24+2+19 = 45
Girls now enrolled in French = 25+20 = 45
Girls now not enrolled in French = 28
-> Total number of students now = 29+45+45+28 = 147
Number of students enrolled in French = 45+45 = 90
-> Required percent = (90/147) *100 = 61.22%
