ATQ, Let the ages of Rohan and Sohan 8 years ago be 5x years and 6x years, respectively. Age of Mohan 8 years ago = 5x−3 years Age of Rohan now = 5x+8 Age of Sohan now = 6x+8 Five years hence: Age of Rohan = 5x+8+5=5x+13 Age of Sohan = 6x+8+5=6x+13 Age of Mohan = 5x+13−3=5x+10 Given: Solving the equation: 7×(5x+10)=6×(6x+13) 35x+70=36x+78 36x−35x=70−78 x=8 Since 10 is the smallest two-digit composite number: Age of Rohan, 10 years hence = 5x+8+10=5×8+8+10=58 years.
