Question

If the ages of kissi and essinam is3:5 and that of essinam and lariba is 3:5 and the sum of all 3 ages is 147 years .What is the difference between the oldest and the youngest age

Answer 1

Step-by-step explanation:

SHORT TRICK;

3:5

3:5= 3*3= 9

5*3= 15

5*5= 25

LET THE AGE OF KISSI BE X = 9X

AGE OF ESSINAM BE 15X

AGE OF LARBIA BE 25X

SUM = 147 YEARS

ACCORDING TO QUESTION

9X + 15X + 25X = 147 YEARS

49X = 147 YEARS

X = 147/49

X = 3 YEARS

AGE OF OLDEST = 3*25= 75

AGE OF YOUNGEST = 3*9 = 27

DIFF. = 75 - 27 = 48 YEARS
