Question

shop a offers a single discount equivalent to two succussive discounts of 25 percent and 20 percent​

Answer 1

Solution:

Let the original price be "x"

$\implies \: x - 0.25x = 0.25x$

$\implies \: 0.75x - 0.20(0.75x) = 0.60x$

$\implies \: x - 0.60x = 0.40x$

♠This can be written as 40%x

♠So the equivalent discount is 40%.
