Question

If suraj's collection of stamps is $20$% less than sant's collection, then by what percent is sant's collection of stamps more than that of suraj's?

Answer 1

Let $x$ and $y$ be Suraj and sants collection of stamps

$x=y-\frac{20}{100}y$

$x=\frac{80}{100}y\Rightarrow y=\frac{100}{80}x$

$\frac{20}{80}\times 100=25\%$

Sant's collection stamps are $25\%$ more than that the Suraj
