1.	Three numbers are in the ratio of 345and three cm is 2400 . There HCF is?
Answer» ANSWER: Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is: A) 40 B) 80 C) 120 D) 200 Answer: A) 40 Explanation: Let the numbers be 3X, 4x and 5x. Then, their L.C.M. = 60x. So, 60x = 2400 or x = 40. The numbers are (3 x 40), (4 x 40) and (5 x 40). Hence, REQUIRED H.C.F. = 40.
