THIS IS A TOUGH ONE BUT I MANAGED TO GET THE ANSWER. there are a number of cuffs and collar pieces which belong to freddy and charlie. there total is 30. freddy and charlie give all of tem to the laundry. freddy collects half the number of cuffs and one-third the number of collars and pays his share of 27 cents. 4cuffs costs 5collars.now tell how much did charlie pay for his share? solution:: let the TOTAL number of the cuffs be X let the TOTAL number of the COLLARS BE be 30-X NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) = X/6 + 10 so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20 by inspection and trial and error we can see that X=12 ((( there is no other way))) now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18 there fore freddy pays 27cents for 12 pieces so charlie will pay ____ cents for his 18 pieces THE ANSWER WILL BE 40.5 CENTS 10. Y X Z Y I DON' REMEMBER THE FULL QN, BUT THE QN WAS TO FIND VALUES X Z OF X Y Z. THE ANSWER IS X=9 ----------------- Y=1 Y X X X Z Z=8 1.There is a escalator and 2 persons move down it.A takes 50 steps and B takes 75 steps while the escalator is moving down. Given that the time taken by A to take 1 step is equal to time taken by B to take 3 steps. Find the no. of steps in the escalator while it is staionary. Solution (not sure): If A takes 1 step in one second, then B takes 3 steps in one second. If A takes t1 seconds to take 50 steps, then B takes 150 steps in t1 seconds. For B, to take 150 steps he requires t1 seconds, then to take 75 steps he requires t1/2 seconds. So now, s1=50, t1 = t1 & s2=75, t2=t1/2 ans= (s1*t2 ~ s2*t1) / (t1 ~ t2) which gives 100. so 100 steps is the answer 2.
