Answer: Option B Explanation: Let the number of boys = x Then, x + 7x/10 = 85 x = 50 No. of girls = 85 - 50 = 35 (i) Number of boys playing only badminton = 50% of boys = 50/100 x 50 = 25 (ii) Number of children playing only table tennis = 40% of total no. of children = 40/100 x 85 = 34 (iii) Total no. of children playing both badminton and table tennis = 12 Hence, number of girls playing only badminton = 85 - (25 + 34 + 12) = 85 - 71 = 14. |
