Answer 1

Hello Dear,

◆ Answer -

Average age = 25 yrs 4.5 months

◆ Explanation -

Initially, sum total age of 14 persons in group is -

Total = number × average

S1 = 14 × 27.75

S1 = 388.5 yrs

Later, sum total age of 12 persons in group is -

S2 = S1 - 2×42

S2 = 388.5 - 84

S2 = 304.5 years

Average age of remaining persons in a group is -

Average = total / number

Average = 304.5 / 12

Average = 25.375 years

Average = 25 yrs 4.5 months

Therefore, average age of remaining persons in a group is 25 yrs 4.5 months.

Hope this helps you...
