2 boxes of chocolate cost $32 less than 5 boxes of sweets.

4 = 2 x 2
$32 x 2 = $64
5 x 2 = 10

Then 4 boxes of chocolates cost $64 less than 10 boxes of sweets.

Now 4 boxes of chocolates cost the same as 6 boxes of sweets.

So this means 6 boxes of sweets cost $64 less than 10 boxes of sweets.

Since the difference is 4 boxes of sweets, then 4 boxes of sweets cost $64.

1 box of sweets = $64 ÷ 4 = $16

6 boxes of sweets = $16 x 6 = $96
From the info above, we can also say that 4 boxes of chocolates cost $96

1 box of chocolates cost $96 ÷ 4 = $24
