If each term in the sum a1+a2+a3+.....+an is either 7 or 77 and the sum equals 336, which of the following could be equal to n?	Choose the correct choice from the following answers:	A) 38	B) 39	C) 40	D) 41	E) 42
Since, there is no 48 in the answer choices (336/7 = 48), we know there is at least one 77.   336 - 77=

<output>259</output>
259   259/7= 
<gadget id="calculator">259/7</gadget>
<output>37</output>
37   37+1= 
<gadget id="calculator">37+1</gadget>
<output>38</output>
38   If 38 wasn't there, I would have subtracted 77 from 259 and continued in a similar way.   Ans. 38
