| Answer» Let the two numbers be x and yAccording to first condition :X +Y =15 ------eq.1According to second condition:1/X +1/Y = 3/10-------eq.2(Cuz its said that their reciprocal.....) Now multiply eq.2 by *3*(so that we can get rid of the denominator 3 in left hand side)Thus we get :3x +3y =10-----eq.3Now taking eq.3Transposing values to get value of X,we getX= 10-3y/3Put X =10-3y/3 in any appropriate eq. and get your answerNote : i used substitution methodYou can use elimination method and cross multiplication method too...Lol..my fingers are paining ??This mic wont work and i cant send pictures ....hope that helpsAsk if you\'ve any doubt | |
