★ Given...✒

Find the single discount equivalent to successive discount of 13% and 15%

★ Solution...✒

d1 +d2 + (d1× d2)/100

Whereas there has been talking about discount therefore both 13% and 15% will be negative

So,

⇝ - 13 - 15 +(-13 × -15) /100

⇝ - 28 + 195/100

⇝ - 28 +1.95

⇝ - 26.05

i.e single discount is 26.05%
