Answer is : 48 years
Explanation:
Let Mukesh's age = 2x or Suresh's age =3x
After 12 years,
\(\frac{2x+12}{3x+12} = \frac{11}{15}\)
\((2x+12) \times 15 = (3x+12) \times 11\)
\(30x +180 =33x +132\)
48 = 3x
x = 16
\(\therefore \text{ The present age of Suresh will be : }3x\)
\(= 3 \times 16\)
\(= 48 \text{ yr}\)
