Question

Pedro is half of Juan age. Miguel is half of Pedro's Age. The addition of the 3 ages is 42. Find the ages

Answer 1

M=P/2

P= J/2

J=2P

M+P+J = 42

P/2 +P + 2P = 42

3.5P = 42

P = 42/3.5 = 12 years old for Pedro

M= P/2 = 6 years old for Miguel

J=2P = 24 years old for Juan

6+12+24 = 42
