Question

The ages of kavya and karthik are 11 years and 14 years.In how many years time will the product of their ages be 304

Answer 1

let the year be x

so,

According to question

(11+x)(14+x)=304

=11(14+x)+x(14+x)=304

=154+11x+14x +x square=304

=154+25x+x^2=304

=25x+x^2=304-154

=25x+x^2=150

now put values for x

x=5

=25(5)+5^2=150

=125+25=150

=150=150

so x=5,

after 5 year product of both ages =304
