<p>prime numbers k and n are each greater than 2 and they differ by 4.if there is no prime number between k and n what is the least possible value of k+n?</p>
<p>Two numbers are 7 and 11. So the value of k+n = 7+11=18. I think?</p>
<p>30
(13+17)</p>
<p>Heisenberg is wrong. The question is asking for the LEAST possible value, which Katherine has said correctly which is 18(7+11)</p>
<p>This one too, if the value of a certain building increased from 1.6 million to 2.0 million what was the percent increase in the value?</p>
<p>Yeah you’re right. My bad</p>
<p>@Asatstudent
The percentage increase is 25%</p>
<p>Yeah the formula is just (profit/cost price) * 100. That gives you 25%</p>
<p>Thank you all</p>
