Answer 2

Step-by-step explanation:

• Let x be the common multiple
• Then, present age of Vijay=2x ; present age of Gautam=3x
• After 5 years, Vijay 's age=2x+5; Gautam's age=3x+5
• Ratio of their ages after 5 years=2x+5/3x+5
• Then, 2x+5/3x+5=3/4
• 4(2x+5)=3(3x+5)
• 8x+20= 9x+15
• 20-15=9x-8x
• 5=x
• therefore,x=5 ;
• Hence present age of Vijay=2x=2×5=10years Present age of Gautam=3x=3×5=15 years
• This is the right answer,If it helped you,plz mark it as Brainliest......pliz
