Question 3
Mona is 11 years and 3 months old.
Jo is 9 years and 8 months old.
Ayesha is 7 years and 7 months old
What is their average age in years and months?
Solution:
Mona is 11 years and 3 months old.
Jo is 9 years and 8 months old.
Ayesha is 7 years and 7 months old
Total age = 11 years + 9 years + 7 years = 27 years
Total months = 3 months + 8 months + 7 months = 18 months
Average age = (27 years + 18 months)/ 3 = 9 years and 6 months
Therefore, their average age is 9 years and 6 months.

Question 5
Rule: If a card has a vowel on one side, then it has an even number on the other side.
(i) 8 (ii) U (iii) V (iv) 6 (v) 5
Which one of these five cards cannot have a 5 on the back?
Solution:
Since U is a vowel, so it cannot have 5 on the back side.
V is consonant, so it can have 5 on back side.
Rest all other are numbers, therefore it cannot have 5 on back side.
Therefore, V can have 5 on the back side.
