 Question 315684: 5 years ago, some was 3 times as old as raju, 10 years leter some would be twice as old as raju, How old are they now?Found 2 solutions by texttutoring, shantysaggu007:Answer by texttutoring(324)   (Show Source): You can put this solution on YOUR website!Let s = some's age Let r = raju's age Now you need to come up with two equations, to solve the two variables: s-5 = 3r s+10 = 2(r+10) Now substitute s=3r+5 into the 2nd equation: 3r+5+10 =2(r+10) 3r+15=2r+20 r=5 Therefore, s=3r+5=3(5)+5=20 Some is 20 years old, and Raju is 5 years old.
