Answer 2

Answer:

₹517.50

Step-by-step explanation:

CP of note books =₹600

the gain desire on the whole=10%

therefore, total SP of the whole books=

100/(100+10) *600=₹660

CP of 1/4 of the book=1/4*600=₹150

loss on it 5%

therefore, SP××××× of it =100/100-5*150=₹142.5

CP of remaining note books =₹600-150=450

SP of remaining note books=₹660-142.5=₹517.50

Ans-₹517.50
