  • A. $1$

  • D. $4$

Answer 1

$1^{st}$ condition

" GDPs of the countries X and Y have grown over the past five years at compounded annual rate of $5\%$ and $6\%$ respectively. "

If country X has growth rate $5$ years back A

Now GDP for $X =A(1+5/100)^{5}$

Now GDP for $Y=B(1+6/100)^{5}$

$2^{nd}$ condition is

" Five years ago, GDP of country X was higher than that of country Y "

But until we know X was actually how much higher than Y

We cannot conclude anything

So, answer is

4) if the question cannot be answered even by using both statements together.
