Then, B gave C and A the same number of marbles they already have. Then C gave A and B the same number of marbles they already have. At the end A,B,and C have equal number of marbles. (i) If x,y,z are the marbles initially with A,B,C respectively. Then the number of marbles B have at the end (a) 2(x-y-z) (b) 4(x-y-z) (c) 2(3y-x-z) (d) x + y-z Ans. (c) (ii) If the total number of marbles are 72, then the number of marbles with A at the starting (a) 20 (b) 30 (c) 32 (d) 39 Ans. (d) 3. If a car starts from A towards B with some velocity. Due to some problem in the engine after traveling 30km, the car goes with 4/5 th of its actual velocity The car reaches B 45 min later to the actual time. If the car engine fails after traveling 45km, the car reaches the destination B 36min late to the actual time What is the initial velocity of car and what is the distance between A and B in km Ans. 20 & 130. 4. A person has Rs 100/- in his pocket, he can as 25 pencils or 15 books. He kept 15% of the money for traveling expenses and purchased 5 pencils.
