Answer: D
5719x to be divisible by 2, 3, and 6 must follow the divisibility rule for 2, 3, and 6.
Divisibility rule for 2: last digit must be an even numbers (0, 2, 4, 6, 8)
Divisibility rule for 3: sum of all digits must be divisible by 3.
Divisibility rule for 6: must follow the divisibility rule for 2 and 3.
Applying the divisibility rule for 6, we now get the sum of all digits to check if this number is divisible by 3.
5+7+1+9+x = 22+x, since we need an even number for the last digit so that it can be divisible by 2, x = 2 so that
22 + 2 = 24, 24 is divisible by 3.

Answer: A
2:3, ratio of men to women. Let k = constant which we will use as multiplier to the ratio
Answer: B
6:5:4 - ratio of apples, banana, & peaches respectively. Let k = constant which we will use as multiplier to the ratio
weight of apple = (6)(15) = 90, weight of banana = (5)(15) = 75, weight of peaches = (4)(15) = 60
weight of apple -...
