If a certain manuscript has 100 pages, of which 40 were revised only once, 10 were revised twice, and the rest required no revisions, what was the total cost of having the manuscript typed?

(A) $430 (B)$620
(C) $650 (D)$680
(E) $770 Do you think that 40 includes 10? Thanks!

PS [#permalink] 15 Jan 2011, 20:04 I thought the the ones receiving 1st review include ones with no review and the ones receiving 2rd review include the one with 1st review and no review. 10*(5+3+3)+(40-10)*(5+3)+(100-40)*5 = 110+240+300 = 650 This is very tricky, and there is answer (C_ that fits my reasoning (650). Can some one please explain why my reasoning is not correct? Math Expert Joined: 02 Sep 2009 Posts: 31304 Followers: 5364 Kudos [?]: 62527 [4] , given: 9457 Re: OG11.

Can some one please explain why my reasoning is not correct? "40 pages were revised once" - so how can 10 pages which were revised TWICE be from a group which was only revised ONCE? Rates for having a manuscript typed at a certain typing service are$5 per page for the first time a page is typed and $3 per page each time a page is revised. If a certain manuscript has 100 pages, of which 40 were revised only once, 10 were revised twice, and the rest required no revisions, what was the total cost of having the manuscript typed? (A)$430
(B) $620 (C)$650
(D) $680 (E)$770

For 100-40-10=50 pages only cost is 5$per page for the first time page is typed - 50*5=250$;
For 40 pages the cost is: first time 5$+ 3$ of the first revision - 40*(5+3)=320$; For 10 pages the cost is: first time 5$ + 3$of the first revision + 3$ of the second revision - 10(5+3+3)=110$; Total: 250+320+110=680$.

OR:
100*5+40*3+10(3+3)=500+120+60=680.

Hope it's clear.

Total cost = 50 * (New) + 40 (New + Revision1) + 10 * (New + Revision1 + Revision2)

Total cost = 50 * 5 + 40 * (5+3) + 10 * (5+3+3)

= 250 + 320 + 110

= 680
