Answer 1

The solution is attached

Answer 2

Answer:

The profit percent is 50

Step-by-step explanation:

Step 1:

Cost price of 1st set of lemons  

= Rs. 1/3

Step 2:

Cost price of 5 lemons = Rs. 5/3

Step 3:

Cost price of 2nd set of lemons

= Rs. ½

Step 4:

Cost price of 5 lemons = Rs. 5/2

Step 5:

So the cost price of 10 lemons

= 5/3 + 5/2

= Rs. 25/6

= Rs. 4.16

Step 6:

Selling price of 10 lemons = Rs. 6

Step 7:

Profit of the vendor = Rs. 6 - Rs. 4  

= Rs. 2

Step 8:

Profit % = 2/4 × 100 = 50 %.
