In a jar there are balls in different colors: blue, red, green and yellow.
The probability of drawing a blue ball is 1/8.
The probability of drawing a red ball is 1/6.
The probability of drawing a green ball is 1/10.
If a jar cannot contain more than 250 balls, how many yellow balls are in the Jar? Choices.
A) 25.  B) 34.  C) 53.  D) 60.  E) 73.
We need to get some number which is less than 250 and exactly divisible by 8,6 and 10   Lets take LCM of three balls 8,6 and 10 = 120.   The probability of drawing a blue ball is 1/8...For every 8 balls we get 1 BLUE ball then out of 120 balls we get 15 BLUE balls.   The probability of drawing a red ball is 1/6...For every 5 balls we get 1 RED ball then out of 120 balls we get 12 REB balls.   The probability of drawing a green ball is 1/10. For every 10 balls we get 1 GREEN ball then out of 120 balls we get 20 GREEN BALLS.   Then out of 120 - ( 15 + 20 + 12 )=

73 YELLOW balls.   IMO option 73. is correct.
