Answer 2

Answer:

Number of boys = 168

Step-by-step explanation:

Let the number of boys and girls be 8x and 5x respectively. Here x is the common factor which gives the ratio 8:5

8x+5x=13x

8x+ 105 = 13x {Since, Number of girls = 105}

13x-8x=105

5x=105

x=21

So, the number of boys = 8x = 8×21 = 168
