Ques - In an examination 52% of the candidates failed in Science 42% in Mathematics and 17% in both. The no. of those who passed in the both subjects, is :

(a) 83%

(b)64%

(c)23%

(d) 55.55%

Solution - Percentage of the candidates failed in Science = 52%

Percentage of the candidates failed in Mathematics = 42%

Percentage of the candidates failed in both = 17%

Percentage of the candidates failed in only Science = 52% - 17%

  = 35%

Percentage of the candidates failed in only Mathematics = 42% - 17%

 = 25%

Percentage of the candidates passed in the both subjects = 100 - 35 - 25 - 17

 = 23%

Hence,

The correct option is (c)23%.
