Question

o rochie costa 137 euro dupa care ajunge la 60 euro. care este procentul de reducere aplicat?

Answer 1

$137 - p\% \ din \ 137=60 \\\\ 137 - \frac{p}{100}*137=60 \\\\ 137-60= \frac{137p}{100} \\\\ 77=\frac{137p}{100} \\\\ p=\frac{77*100}{137}= \frac{7700}{137} \\\\ \boxed{p=56,2 \% }$

Answer 2

137-x%*137=60 -->
x=7700/137
