Answer:
Selling price of watch A and watch B= Rs. 425
Let cost price of watch A=x
Profit =10%
We need to first find the overall cost price.
Two varieties of tea, costing Rs. 40 and 50 kg respectively, were mixed in the ratio 3:2.
Thus, overall cost = Weighted average of the two individual costs = 3(40)+2(50)/(3+2) = Rs.44 per kg.
Now, selling price per kg = Rs. 48
Per kg profit = 48 - 44 = Rs. 4
Thus, profit% = (profit/cost) x 100 = (4/44)*100 = 9.09%
