answer:

hahahahaha

yeh nalayak pta ni kon hai

since we have given that

percentage of the candidates passed in english = 63%

percentage of the candidates passed in maths = 65%

percentage of the candidates failed in both subjects = 27%

percentage of the candidates failed in english = 100-63 = 37%

percentage of the candidates failed in maths = 100 - 65 = 35%

so, percentage of the candidates that failed in maths or english is given by

37% + 35% - 27%

= 45%

so, percentage of the candidates that passed in both subjects is given by

100%-45% = 55%

hence, there are 55% of students who passed in both subjects.
