Answer 2

Step-by-step explanation:

A stationer bought exercise books =2000

stationer bought exercise books donation = 200

remaining the exercise books = 2000-200 =1800

Let the cost price = x

each of the remaining exercise booksat Rs 10 more than the cost price of each = 10+x

Now,

remaining the exercise books = cp +profit%of cp

or, 1800(10+x) = 2000x+2000x×8/100

or, 18000 +1800x-2000x=160x

or, 18000=360x

or, 18000/360=x

so, x =50

cost price of each exercise book be x= Rs50

the remaining 5 books pries = 5x =5×50=Rs250
