I am having a little mental lapse.

If the average score of p students is 70 and the average score of n students is 92, and the average of the scores of p and n is 86, what is p/n?

(70p + 92n)/ ( p + n ) = 86

70p + 92n = 86(p+n)

70p + 92n = 86p +86n

92n = 16p + 86n

6n = 16p

p = 3/8n

n= 8/3p

Where do I go from here (sorry was awake for whole night)

Thanks
