If the number of white balls in a box are 6 times the black balls, which of the below is the total number of balls, if there are 8 black balls in the box? Choose the correct choice from the following choices.
A) A - 56	B) B - 57	C) C - 58	D) D - 59	E) E - 60
Let the number of black balls = x and the number of white balls = 6x Then, total number of balls in the box = x + 6x = 7x i.e., the total number of balls must be a multiple of 7 From the given choices, only 56 is the multiple of 7. Hence, 56 are the number of balls in the box. A - 56nswer is A - 56.
