8) Costcorp sells packets of mints to shop owners.
On Monday three shop owners buy mints from
Costcorp
Each shop owner buys small packets, medium packets
and large packets of mints.
Alan buys 400 packets of mints.
32 % are small packets.
40 % are large packets.
Beryl buys 500 packets of mints.
3/10 are small packets.
1/10 are large packets.
Charlie buys 150 small packets of mints so that
number of small packets : number of medium packets =
3:4
Work out the total number of medium packets of mints
these shop owners buy.
You must show all your working

502 medium packets

Step-by-step explanation: First off you need to understand what the ratios, fractions, and percentages represent. It might be best to break them up into categories to organize your results after turning them to percentages.

Allan - 32% small, 40% large, the other percentage must be 28 (100 - 72). Now to find out what 28% of 400 is. To get your answer, multiply 400 by 0.28. You'll end up with 112 medium packets

Beryl - 30% (3/10) small, 10% (1/10) large, 60% medium. Finding 60% of 500 is simple. Multiply 500 by 0.6 to get 300 medium packets.

Charlie - small to medium ; 3:4. If Charlie only bought 150 mints, it's simple to split it evenly with the ratio given to end up with 60 and 90. (ratios aren't my strong point, I may be wrong here)

If you add up 112, 300, and 90, you'll have an answer of 502

70,000 + 6,000 + 800 + 30
