Mrs. Lata was 3 times as old as her son 8 years ago. Their total age is 64 years now. How old (in years) is Mrs. Lata now?
Let Mrs. Lata's age = $$x$$ years
=> Son's age = $$(64-x)$$ years
According to ques,
=> $$3(64-x-8)=(x-8)$$
=> $$3(56-x)=x-8$$
=> $$168-3x=x-8$$
=> $$3x+x=168+8$$
=> $$4x=176$$
=> $$x=\frac{176}{4}=44$$ years
=> Ans - (D)
