1. If the ratio of the ages of Kissi and Esinam is 3:5 and that of Esinam and Lariba is 3:5 and

the sum of the ages of all 3 is 147 years, what is the age difference between oldest the

youngest?

37 years difference.

Step-by-step explanation:

K = Kissi

k = Age of Kissi

E = Esinam

e = Age of Esinam

L = Lariba

l = Age of Lariba

k + e + l = 147

K : E

3 : 5 → (*3) → 12 : 15

E : L

3 : 5 → (*5) → 15 : 25

K : E : L

12 : 15 : 25

12 + 15 + 25 = 52

147/52 = 2.8269 ...

K is the young since out of the three part ratio, 12 is the smallest and likewise, L is the oldest.

k = 12 * 2.8269 ... = 33.923 ... → 34 y/o

e = 15 * 2.8269 ... = 42.40 ... → 42 y/o

l = 25 * 2.8269 ... = 70.673 ... → 71 y/o

∴ The difference between the youngest and oldest is:

71 - 34 = 37
