It would be easier to translate this into mathematical terms first. Let n = the unknown number
6n <span>> n + 20
Subtracting both sides by n to simplify: 6n - n </span><span>> n + 20 - n </span>5n <span>> 20 </span><span> Dividing both sides by 5: 5n/5 </span><span>> 20/5 </span>n <span>> 4 </span><span> Among the choices, the correct one is the second choice.
