A book seller sells a book at a profit of 10%. If he had bought it at 4% less and sold it for Rs.6 more, he would have gained 1834
. The cost price of the book is
ARs.130
BRs.140
CRs.150
DRs.160

Correct Answer:

C) Rs.150

Explanation:

Let CP = x

The, SP =110x100=Rs.11x10

Now, CP = 96% of x =96x100=Rs.24x25

Now according to the question,

SP = Rs.(11x10+6)

(11x10+6)=11834

11x+6010=475400×24x25=57x50

550x+3000=570x
20x=3000
X=300020=150

CP = 150
