The ratio of length of two refill is 9:8.2nd refill got damaged when only half length of 2nd refill get used.The ratio of total no. of pages written by both refill.	Select the correct option:	A) 8:3	B) 6:5	C) 9:8	D) 9:4	E) 5:4
the no. of page written is directly proportional to length of refill.   so, initial no. of page to be write =9x,8x.   now,2nd refill only can write 4x page   so new ratio of page written =9x/4x=9:4.   answer 9:4
