Question

2 पुस्तक ₹200 प्रति पुस्तक की दर से खरीदी गई उसमें से एक को 10 पर्सेंट लाभ तथा दूसरी को 5% हानि पर बेचा गया यथार्थ लाभ ज्ञात करें

Answer 1

Answer:

SP of each book = Rs. 200

Total SP =200+200=400Rs.

For 1st book:-

profit %=10%

10/100=(profit*100)xCP

therefore, I on further solving we get

CP/profit=1000

CP/SP-CP=1000

CP/200-CP=1000

(CP/200)-(CP/CP)=1000

(CP/200)-1=1000

CP/200=1001

CP=200200Rs.

For 2nd book :-

let CP be x

loss%=5%

5/100=(loss*100)/CP

therefore on further solving we get

y/loss=2000

y(y-200) =2000

now find the value of y

and add y and 200200

you'll get total cp

now observe, cp>sp,find loss

other wise find profit

profit =sp-cp

loss=cp-sp

profit %=(profit *100)/cp

loss%=(loss*100)cp
