Working together, printer A and printer B would finish the task in 24 minutes. Printer A alone would finish the task in 60 minutes. How many pages does the task contain if printer B prints 5 pages a minute more than printer A ? A. 600 B. 800 C. 1000 D. 1200 E. 1500 I know this question is relatively symol if make an equation in one vaibale ... I tried to do it by applying the fundamental of A = Jobs per min * time ( the way we typically solve the work problems ) and i was stuck
I did jobs per minute A , 1/60 combined rate = 1/24
so rate of b = 1/24  1/60 = 1/40
but could not arrive at the solution ... i tried to form the equation by assuming x as the total numbe of pages So x/60+ x+5/40 = cld nt take ot forward from here kindly see where am I losing the track !

B in a minute=x/40 A in a minute=x/60 then, x/40x/60=5

For example, say printer A needs t minutes to print 1 page and printer B needs m minutes to print 1 page, then the rate of printer A would be job/time=1/t pages per minute and the rate of printer B would be 1/m pages per minute (rate is a reciprocal of time, so 1/t=a and 1/m=b). In this case the equation would be 24(1/t+1/m)=x. Hope it's clear.

First thing i did was i found out time that is required to B to complete the task alone: 1/241/60=3/120=1/40. Then i looked at the information which states that the rate of B is 5+ page than that of A so, lets say x is the number of pages printed by A per minute, so the task consists of 60*x or 40*(x+5) pages. I can make an equation: 60x=40(x+5), 20x=200, x=10, total number of pages is 60*10=600 or 40*15=600 Answer is A. It is clear but it took me about 3 min to do it, does it because i am doing it slow or i am using longer route?

A take 60 min. B takes 40 min to complete a task. Now, divide the values given in option (in Ans) to get the rate per min. option A: 600 / 10 = 60 & 600/40 = 15...> this satisfies the condition given in question stem that printer B prints 5 pages a minute more than printer A ?
. therefore A

A does in one minute =x pages Therefore, in 60 minutes=60x pages
B does in one minute= x+5 In 24 minutes both do 60x pages 24x+24(x+5)=60x X=10 total work=60*10=600 pages

Easiest way to do this: Machine A and B can do the task in 24 minutes thus Rate of A and B = 1/24. Now given A can do the task in 60 minutes therefore Rate of A= 1/60. We know that Rate of A and B = Rate of A + Rate of B therefore Rate of B= Rate of A and B  Rate of A = 1/241/60= 1/40. Now we know that Rate of B = 1/40 thus B can do the work in 40 minutes. Let pages printed per minute by A = x, given that pages printed by B per minute is 5 more than that of A Pages printed by B per minute = x+5 Now Complete task is done by A in 60 minutes therefore total number of pages printed by A = x * 60 Also Complete task is done by B in 40 minutes therefore total number of pages printed by B = (x+5) * 40 therefore x * 60 = (x+5) * 40 therefore x=10 thus the total number of pages in task = x*60 = 10*60 = 600

Okay..this is how I did it.. Let the task(number of pages) be 120x(LCM of all numbers given in the problem)..
A and B take 24 minutes to complete it..thus, pages per min = 5x A's pages per minute = 2x B's pages per minute = 3x
Difference 3x  2x = 5 => x = 5 Thus, 120x = 600..(A)

Another approach after getting rate for B as rate of B = 1/40 let A prints x pages a minute , then B will print x+5pages a minute A work for 60 minutes and B work for 40 minutes alone and so ,they are able to print same no. of pages thus, 40(x+5) = 60x 40x+200 =60x 20x=200 x=10 thus total no of pages = 60x or 40(x+5) =600 pages Ans A

but could not arrive at the solution ... i tried to form the equation by assuming x as the total numbe of pages So x/60+ x+5/40 = cld nt take ot forward from here kindly see where am I losing the track ! Given that, A can finish in 60 minutes, combined 24 minutes. so, the rate of B = 1/24 1/60 equals 1/40 thus B takes 40 minutes to accomplish the job alone. As B can finish 5 more pages than A in a minute. Let, A can print x pages per minutes then, B = x+5 60x = 40( x+5) x= 10 Thus total number of pages together can print = 60 *10 A. 600

A. 600 B. 800 C. 1000 D. 1200 E. 1500 Let the total work be 120 units So, Efficiency of A and B is 5 units/min & Efficiency of A is 2 units/min Thus , the efficiency of B is 3 units/min So, 1unit/min = 5 Pages Hence, 120 Units = 120*5 => 600 Units, Answer must be (A)

[quote="gauravnagpal"]Working together, printer A and printer B would finish the task in 24 minutes. Printer A alone would finish the task in 60 minutes. How many pages does the task contain if printer B prints 5 pages a minute more than printer A ? A. 600 B. 800 C. 1000 D. 1200 E. 1500 Total task = 60A B = A+5 24(A+B) = 60A 24(A+A+5) = 60A 24(2A+5)=60A 48A+120= 60A 120=12A A=10 Total tasks =60A = 600. Check the answers to confirm Hence option A is the answer.
