Solution 2
Let, 49 equates to the x% of 70.
Therefore, 70∗x %=49
70∗x
100 =49
x= 49∗100
70
x=7∗10=70
Hence, 49 is 70% of the 70.

Solution 3.B
Total number of cereal bars in a carton is 150.
Number of students in the class is 20.
The number of cereal bars for each student is
total number of cereal bars
number of students = 150
20
Hence, when 150 cereal bars are distributed to the whole class then each student will get 1
20
of 150 cereal bars. Thus, the average cereal bars for each student is 15
2 .
Solution 4
Samuel gave three £50 notes for the tickets that means he paid (3*£50) = £150 for the tickets.
He received £4.20 change after paying £150.
So, the net spending on tickets is £ (150-4.20) = £145.80.
Hence, the price for each ticket is £ 145.80
3 =£ 48.60.

Solution 6
Solution 6.A
The amount of spending with discount is £100.
The amount of discount is 20%.
Hence, the total price without discount is
£ 100
(1− 20
100 )
= £ 100

= £ 100∗5
4 =£ 125.
Now, the total savings is £ (125-100) = £25.
Solution 6.B
The average savings amount for 4 hairdos is £ 25
4 =£ 6.25.
Solution 7
Solution 7.A
