Question

An article is listed at rs 65.a customer bought this article for rs56.16 with two successive discount of which one is 10%.the other discount will be

Answer 1

sp=56.16, cp=65, d1=10%

let d2=x,

sp=cp(1-d1/100)(1-d2/100)

56.16=65(1-10/100)(1-x/100)

56.16=65(90/100)(1-x/100)

(5616/100)*(100/90)=65(1-x/100)

5616/90=65(1-x/100)

5616/(90*65)=1-x/100

5616/5850=1-x/100

(5616/5850)-1=(-x/100)

-234= -(x/100)

234/5850=x/100

23400/5850=x

4=x

d2=4%
