I'm looking for students who wish to opt for online classes for math-any syllabus (up to 12th grade)
Let's assume P and Q's present ages are pp and qq
So p:q=5:7p:q=5:7 ie p/q=5/7p/q=5/7 ie p=5/7×qp=5/7×q
As per second statement
q−(p+6)=2q−(p+6)=2
{Replace p's value from eqn 1 into eqn 2}
q−(5/7×q+6)=2q−(5/7×q+6)=2
ie 2/7×q=82/7×q=8
ie q=8×7/2=28q=8×7/2=28
So p=20p=20
So total of their present age is 48.
