The average age of 19 boys in a class = 21 years
Sum total of ages of 19 boys = 19 × 21 years = 399 years
The average age of 19 boys and teacher in a class = 21 years
Sum total of ages of 19 boys and teacher = 20 × 22 years = 440 years
? Age of teacher = Sum total of ages of 19 boys and teacher - Sum total of ages of 19 boys
Age of teacher = ( 440 ? 399 ) years = 41 years
All others are divisible by 13.
25 = 32,
Similarly, 35 = 243
both I and II follows.
The given letter series in below pattern.
b b y t
After completing the pattern, we will get complete letter series.
b b y t / b by t / b b yt
