C.P. of two books is same. One sold at 15% profit and the other for ₹ 4800 more than the first. If the net profit is 20% then find the C.P. of each book?

Answer»

₹48000
₹480
₹4800
₹38000

SOLUTION :Let `CP_(1)= 100 CP_(2) = 100`
OVERALL `CP = 200`
`SP_(1) = 115,`
overall SP = 240
`SP_(2)`= overall, SP - SPI = 240 -115 = 125`
Difference in SP = 125-115= 10
Therefore CP `= 48000 xx 100//10 = ₹ 48000`.
Alternate Solution:
As priceof both booksis same one is sold at 15% so
other must besold at 25% to make overall profit of 20%
`therefore ` 10%$ = 4800`
`rArr 100% = 48000`
= Priceof 1 book.
