Selling price of each plain books and lined books sold by store B is Rs. 250 and Rs. 175 respectively. Then, find the total amount earned by store B on selling these books if 60% of lined books are sold by the store ?

Number of total books sold by store B

$= 5000 imes frac{{40}}{{100}} = 2000$

Number of lined books sold

Total amount earned = Rs. (800 × 250 + 1200 × 175) = Rs. 4.1 lac
