4 identical printing machines can print a combined total of 800 posters in 1 hour.

If only 3 machines are available, how long will it have taken to print 800 posters?

• 1 hour 20 minutes

• 2 hours

• 1 hour 30 minutes

• 1 hour

• 30 minutes

Answer explanation

Each printer can print 200 newsletters per hour (800/4).

In 1 hour, the 3 printers will print 600 newsletters (200 × 3).

After 1 hour, 200 newsletters will still need to be printed (800 – 600).

Each printer will therefore need to print a further 66 newsletters (200/3).

If they can print 200 in 1 hour, it will take 20 minutes to print 66 (60 mins/3).

The 3 printers will therefore be able to print the 800 newsletters in 1 hour 20 minutes.

Two balls A and B rotate along a circular track. Ball A makes 3 full rotations in 33 minutes. Ball B makes 8 full rotations in 56 minutes. If they start rotating now from the same point, when will they be at the same starting point again?

• 77 min

• 21 min

• 91 min

• 94 min

• 13 min

Answer explanation

Ball A makes 3 full rotations in 33 minutes, we know one rotation is 11 minutes ( 33/3 = 11)

Ball B makes 8 full rotations in 56 minutes, hence one rotation is 7 minutes.

As they start at the same time, to find the time where they be at the start point again, we find the Lowest Common Multiple (LCM) of 11 and 7, which gives us 11 x 7 = 77 minutes

Three friends William, Xavier and Yusuf are standing in a line. If William is to the right of Xavier and Yusuf is to the left of William, which one of the following statements must be true?

• Yusuf is furthest to the left.

• William is in the middle.

• William is furthest to the right.

• Xavier is furthest to the right.

Answer explanation

We are told that William is to the right of Xavier, and if Yusuf is to the left of William, William must be to the right of Yusuf. 

William is therefore to the right of both of the others and so must be furthest to the right.
