Menta Posted January 31, 2014 Report Share Posted January 31, 2014 Tatal este peste mama sau cel mai probabil zis cu ceva in mama. Quote Link to comment Share on other sites More sharing options...
GraFFik Posted January 31, 2014 Report Share Posted January 31, 2014 Nu va speriati, aceasta problema nu este chiar asa grea cum pare si se poate rezolva matematicCopilul are azi X ani si mama Y ani, stim ca mama are cu 21 de ani mai mult decit copilul. Deci: X + 21 = Y Stim ca peste 6 ani copilul va fi de 5 ori mai tinar decit mama. Deci putem scrie urmatoarea ecuatie: 5 (X + 6) = Y + 6 Inlocuind Y cu valoarea din prima ecuatie, rezulta: 5 (X + 6) = X + 21 + 6 5X + 30 = X + 27 5X - X = 27 - 30 4X = -3 X = -3/4 Copilul are azi -3/4 dintr-un an deci are -9 luni. Din punct de vedere matematic putem confirma si dovedi ca in acest moment mama concepe copilul. Rezultatul: TATA ESTE PESTE MAMACopy paste...

curiosul Posted January 31, 2014 Report Share Posted January 31, 2014 (edited) m = 21 + cc + 6 = m / 5c+6 = (21 + c) / 5c = [(21 + c) / 5] - 60 = ... Nu da Edited January 31, 2014 by curiosul Quote Link to comment Share on other sites More sharing options...
.darky Posted January 31, 2014 Report Share Posted January 31, 2014 (edited) M=C+21M+6=5*(C+6) > M=5*C+24Prin substitutie matematica, rezultatul va fi C=-3/4 (-9 luni) iar rezultatul final va fi... Edited January 31, 2014 by .darky Quote Link to comment Share on other sites More sharing options...
