Equal weights of two alloys containing tin, copper and lead in the ratio 6:8:7 and 1:2:4 are melted and mixed together. What is the ratio of tin, copper and lead in the resultant alloy? Select the correct option:	A) 11:8:3	B) 3:1:8	C) 17:28:27	D) 9:4: 11	E) 9:14: 11
Let the weight of the two alloys be w each   Required ratio =   (6w/21+1w/7): (8w/21+2w/7 ): (7w/21+4w/7)   = 9w/21 : 14w/21 : 11w/21   = 9:14: 11   ANSW9:14: 11R:9:14: 11
