Best ResponseYou've already chosen the best response.0Why 3 equations? The question is "how old are WE now?". Is it not that now, We are 70 yearsold? It doesn't ask how old am I and how old is my sister now. Am I right or am I crazy??

Best ResponseYou've already chosen the best response.1and he is 4 times older than the past age of his sister. then his age and his sister's age will be 4*x/2 and x

Best ResponseYou've already chosen the best response.1all I understand that that if the past ages of boy and his sister consider x and x/2 respectively then their present age is 3x

sohailiftikhar

Best ResponseYou've already chosen the best response.1so let make equations past ages let at 1 year their ages were x+x/2=3x/2 now after one more year it will be x+1+x+1/2=3x+2/2 and after 15 year their ages are x+15+x+15/2=100 does it make sense?
