Given, 1dz=Rs 375
Therefore, 20 dz= 20 * 375= Rs 7500---------(CP)
Now, each toy is sold for Rs 33
1 dz = 12 toys
Then, 20 dz= 20*12=240 toys
So, total SP, 240*33= Rs 7920--------------(SP)
Now, Profit % (P%)= [P/CP] *100
[(SP-CP)/CP] *100
[(7920-7500)/7500] *100
(420/100)*100
=5.6% profit

Number of toys purchased = 20 dozens
                                       = (20 *12 ) toys
                                       = 240 toys.
cost price  of 12 toys = Rs. 375
therefore , cost price of 1 toy = Rs. 31.25
therefore , cost price of 240 toys = 240 * 31.25
                                                = Rs. 7500
selling price of 1 toy = Rs. 33
therefore , selling price of 240 toys = 240 * 33
                                                   = Rs. 7920
profit made = selling price - cost price 
                 = Rs. (7920 - 7500)
                 = Rs. 420
therefore , profit percent = (profit / cost price) * 100
                                   = (420 / 7500 ) * 100
                                   = 5.6 %
ANS) the profit is 5.6 %.
