Answer 1

Step-by-step explanation:

Let us assume that the woman purchased x toffees at Rs 2.50 /dozen costing 2.5x/12 and another x toffees for Rs 3.00 per score costing Rs 3x/20. So the total cost is Rs 2.5x/12+3x/20= (25+18)x/120 = Rs 43x/120.So, by selling @ Rs 3.6 per score, the total amount she gets from the sale of 2x toffees = (2x/20)3.6=7.2x/120Therefore the profit she gets (algebraically) = 7.2x/20-43x/120 = (43.2x-43x)/120=0.2x/120. But this is equal to the actual profit of Rs 10.Therefore the profit she gets (algebraically) = 7.2x/20-43x/120 = (43.2x-43x)/120=0.2x/120. But this is equal to the actual profit of Rs 10.

Therefore, 0.2x/120 =10 or

x=10*120/0.2 =6000. So the number of toffees she purchased =2x= 2*6000 = 12000

Equal number of toffees have been purchased at the price of Rs.2.50 per dozen and Rs.3.00 per score.As one score is equal to 20 and one dozen is equal to 12 the price of first lot of toffees in Rs. per score:= Prize per dozen*(20/12) = 2.50*(20/12) = 50.00/12Therefore the average purchase price in Rs/score of purchasing total number of toffees:

(50.00/12 + 3.00)/2 = (86/12)/2 = 43/12 Rs./score

The toffees are sold at Rs.3.60 per score:Average profit (gains) per score of toffees assuming all toffees purchased are sold:

= (Average purchase price/score) - (Selling price/score) = 3.60 - 43/12 = 43.2/12 - 43/12 = 0.2/12 Rs./score

Therefore profit per toffee = (0.2/12)/20 = 0.1/120 = 1/1200

The total profit is Rs.10.00.

Therefore total number of toffees = 10.00/(profit per toffee)

= 10.00/(1/1200) = 12000

Answer: She bought 12000 toffees.
