The number of boys and in a class are in the ratio 7:5.The number of boys is 8 more than the number of . What is the total class strength?
Let the no. of be 5x No. of boys=7x According to the question 5x+8=7x 7x-5x=8 2x=8 x=8/2 x=4 No. of =54=20 no. of boys=74 or 5*4+8=28 Hence the total strength of the class is 20+28=48
