Answer:
Loose sweets are of better value
Step-by-step explanation:
<u>Packed</u>
120 g = £1.49
price per gram = £1.49/120= £0.0124
<u>Loose</u>
100 g = £0.89
price per gram= 0.89/100= £0.0089
Comparing prices per gram, we can see loose sweets cost less (0.0089<0.0124), so is better value
416.67 pounds of food should be given all five lions each day
<em><u>Solution:</u></em>
Given that, three adult lions together eat 250 pounds of food a day
Thus, 3 adult lions = 250 pounds of food per day
Two more adult lions joined the group and ate food at the same rate as the original three
Now number of adult lions = 3 adult lions + 2 adult lions = 5 adult lions
Let "x" be the food ate by 5 adult lions
Thus we can say,
3 adult lions = 250 pounds of food per day
5 adult lions = "x" pounds of food per day
This forms a proportion and we can solve the sum by cross multiplying
Thus 416.67 pounds of food should be given all five lions each day
<u>Answer:
</u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution:
</u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled =
Time it will take to fill the pool = 748 hrs
