1970 --> Boris age was 26 years ....tsmith93 wrote:Boris was 26 years old in 1970, when his daughter, Olga, was born. In what year was Boris exactly 3 times as old as Olga?
olga born
let after x years bois will be 3 times her daughter age
so 26+x = 3x --> 2x = 26 --> x= 13
so in year 1970 +13 = 1983 Boris will be xactly 3 times as old as Olga

Now,in 1970 age of Olga = 0yearstsmith93 wrote:Boris was 26 years old in 1970, when his daughter, Olga, was born. In what year was Boris exactly 3 times as old as Olga?
Let x years be passed
So,age of Boris = 26 + x
age of Olga = x
Now,Boris exactly 3 times as old as Olga implies
26 + x =3x
Hence,2x =26
x=13
Hence,Age of Olga is 13years
Age of Boris = 26 +13 =39 years
[spoiler]
Year = 1970 + x
=1970 + 13 =1983[/spoiler]
It takes time and effort to explain, so if my comment helped you please press Thanks button
