Average Practice Test 4

Question : 5 of 40

Marks: +1, -0

Solution:

Average age of 7 children = 12 years

Total ages of 7 children = 12 × 7 = 84 years

Age of 1 child who died = 6 years

Total ages of remaining 6 children = 84 – 6 = 78 years

∴ Average age of 6 children

=\frac{78}{6}

= 13 years

∴ Average age of 6 children after 5 years = 13 + 5 = 18 years
