Question
In a classroom there are 13 boys and 11 girls. Average
age of each boy and each girl is 23 years and 17 years respectively. The sum of ages of all the boys, girls and a teacher whose age is ‘x’ years is 540 years. Find the value of ‘x’.Solution
Sum of ages of all boys = 13 x 23 = 299 Sum of ages of all girls = 11 x 17 = 187 So, 299 + 187 + x = 540 => x = 54
