Two Copiers are being used to produce 2400 copies of a 1-page document. One Copier runs at 150% of the speed of the other. How many copies should be made on the faster copier so that both copiers will finish the same time?
Read Solution (Total 7)
-
- 1440
Let the speed of one copier be x
Speed of other copier 150x/100
Ratio of speed = 1:150/100 = 2:3
copies made on faster copier = 3/5 *2400
= 1440

- 150:100=>3:2
3x+2x=2400 =>same time finish
x=480
so faster copier(3x)=1440 copies

- tow copies are produces 2400
first copier produces 150% fast means 2400/2=1200+600=1800
second copier produce =600 - 10 years agoHelpfull: Yes(4) No(5)
- speed of copier1----x
speed of 2-----150/100x
ratio-----2:3
no. of copies of 2nd ------- 3/5*2400=1440 - 10 years agoHelpfull: Yes(4) No(0)
- 150:100= x:(2400-x)
150/100 = x/(2400-x)
x=1440

- A+B=2400
A+150/100A=2400
100A+150A/100=2400
250A/100=2400
5/2A=2400
A=960
A+B=2400
960+B=2400
B=2400-960
B=1440 - 8 years agoHelpfull: Yes(1) No(0)
- 3:2
3+2 = 5
2400/5=480
480*3=1440
480*2=960
1440 & 960 - 10 years agoHelpfull: Yes(0) No(1)
