00:00:01.600 --> 00:00:04.360
A shop sells these sweets.
00:00:05.480 --> 00:00:08.320
And we can see in the picture three different types of sweets.
00:00:08.720 --> 00:00:14.560
One for two p, one for five p and one for 10p.
00:00:14.560 --> 00:00:17.600
Abdul spends exactly 20p on sweets.
00:00:18.680 --> 00:00:20.800
Tick the bag of sweets he buys.
00:00:22.760 --> 00:00:26.240
To begin with, we’re told that the shop sells these sweets.
00:00:26.240 --> 00:00:28.440
And we’re shown three pictures of sweets.
00:00:29.200 --> 00:00:33.080
There’s a sweet with a wrapper on it that’s labelled two p.
00:00:34.160 --> 00:00:37.600
We’ve got a lollipop that’s labelled five p.
00:00:38.760 --> 00:00:42.480
And we have what looks like a jelly sweet which costs 10p.
00:00:44.040 --> 00:00:46.640
We’re then told that Abdul buys some sweets.
00:00:47.560 --> 00:00:51.320
We don’t know exactly which out of the three sweets he decides to buy.
00:00:52.040 --> 00:00:57.000
But we are given a clue because we’re told he spends exactly 20p on sweets.
00:00:57.480 --> 00:01:02.320
So whichever sweets he buys, the total of them comes to 20p.
00:01:03.880 --> 00:01:07.560
We’re then given a picture of four different bags of sweets.
00:01:08.080 --> 00:01:10.560
And we need to tick the bag of sweets that he buys.
00:01:11.760 --> 00:01:15.760
Which of these bags would cost 20p if he bought it from the shop?
00:01:17.080 --> 00:01:26.560
The first bag contains a lollipop, which we know costs five p, and a jelly sweet, which costs 10p.
00:01:28.320 --> 00:01:34.520
What’s the total of 10 and five?
00:01:36.400 --> 00:01:38.080
10 plus five equals 15.
00:01:39.400 --> 00:01:43.400
And so, the price of the first bag of sweets is 15p.
00:01:44.640 --> 00:01:46.840
This is less than 20p.
00:01:47.400 --> 00:01:50.240
And so, we know this is not the bag that Abdul buys.
00:01:51.440 --> 00:01:53.680
Let’s have a look at the sweets in the second bag.
00:01:54.960 --> 00:01:59.440
We have two lollipops, which we know costs five p each.
00:02:00.640 --> 00:02:04.240
And also, we have a jelly sweet again, and this is 10p.
00:02:06.840 --> 00:02:10.840
What’s the total of 10 plus five plus five?
00:02:11.480 --> 00:02:15.640
Well, we know that five plus five or five doubled equals 10.
00:02:16.320 --> 00:02:20.480
So we know the answer is going to be worth two lots of 10.
00:02:20.880 --> 00:02:23.800
10 plus 10 equals 20.
00:02:24.920 --> 00:02:28.400
The cost of the second bag of sweets is 20p.
00:02:29.520 --> 00:02:32.120
This must be the bag that Abdul buys.
00:02:33.200 --> 00:02:36.200
So let’s tick it to show that it’s the correct answer.
00:02:37.400 --> 00:02:39.600
It’s always good to check that an answer is correct.
00:02:40.040 --> 00:02:42.440
So let’s just look at the final two bags.
00:02:43.200 --> 00:02:56.040
The third bag contains a lollipop for five p, a wrapped sweet for two p, and another jellied sweet for 10p.
00:02:56.040 --> 00:03:03.360
Five plus two is seven, and we know 10 plus seven equals 17.
00:03:04.480 --> 00:03:07.440
The third bag costs 17 pence.
00:03:08.240 --> 00:03:11.360
And in the final bag of sweets, we have the two cheapest sweets.
00:03:12.000 --> 00:03:17.040
We have a lollipop for five p and a wrapped sweet for two p.
00:03:18.520 --> 00:03:21.200
Five plus two equals seven.
00:03:21.920 --> 00:03:25.080
So the cost of the final bag of sweets is seven pence.
00:03:25.960 --> 00:03:27.600
So we were right with our answer!
00:03:28.720 --> 00:03:32.160
We know Abdul spends exactly 20p on sweets.
00:03:32.920 --> 00:03:39.520
And so the bag of sweets that he buys is the one that contains two lollipops and a jelly sweet.
