the mean age if four women is 19yr 11month.
When the fifth woman joins them, the average age of all five is 20yr 7month.
How old is the fifth woman.
:
Convert the ages to months
19(12) + 11 = 239 mon
20(12) + 7 = 247 mon
:
let x = age of the 5th woman in monts
= 247
956 + x = 247 * 5
x = 1235 - 956
x = 279 month is the age of the 5th girl
Find the age in yrs using long division; 279/12
I got 23 yrs, 3 months
