Question

A retailer purchased 25 identical toys for rsP and sold some of them for rsP.If he calculated his profit as 8%, with selling price insted of cost price then how many toys did he sell.​

Answer 1

Answer:

23

Step-by-step explanation:

25 identical toys are Rs.P.

one toy = Rs.P/25

profit % = (sp-cp)/cp

In question said to change the base from cp to sp

8/100 = (p - xp/25) / p

solve for x,

then x=23.

Answer 2

Answer:

23

there are 25 toys

cost of 25 toys is p rs

so cost of 1 toy is p/25 rs

we don't know how many toys was sold so

let take it as "x"

but the price p rs

he cost 8% profit by miss calculating by using sp as base instead of cp

eqn would be

8/100 = (xp/25 -p)/p

x=23
