Question

Find the single discount equivalent to suecessive discount of 13% and 15%​

Answer 1

Answer:

For this type of question

u should use this trick formula

d1+d2+ (d1xd2)/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%
