12 years ago, the ratio of age of A and B was 2 : 3. If the ratio of their present age is 5 : 6, then what will be the total of their present age.
Answer & explanation
Correct answer: option 3
A : B
2 : 3 ( 12 years ago )
↓
5 : 6 ( present )
\(\frac{A}{B}\) =\(\frac{2}{3}\)
let age of A = 2x and age of B = 3x
Now , according to question
\(\frac{2x+12}{3x+12}\) = \(\frac{5}{6}\)
12x + 72 = 15x + 60
3x = 12
X = 4
so,
A's Present age = 2 x 4 +12 = 20 years
B's Present age = 3 x 4 +12 = 24 years
total of their present age = 20 + 24 = 44 years
