Let's assume the cost price of the tea-set is x and the cost price of the lemon-set is y.

Selling at Loss and Gain
When the tea-set is sold at a 5% loss, the selling price becomes 0.95x. On the other hand, when the lemon-set is sold at a 15% gain, the selling price becomes 1.15y. The total gain from these sales is 7.

Selling at Gain and Gain
When the tea-set is sold at a 5% gain, the selling price becomes 1.05x. Similarly, when the lemon-set is sold at a 10% gain, the selling price becomes 1.10y. The total gain from these sales is 13.

Forming Equations
We can form the following equations based on the given information:

0.95x + 1.15y = x + y + 7 (Equation 1)
1.05x + 1.10y = x + y + 13 (Equation 2)

Simplifying the Equations
We can simplify Equation 1 by subtracting x and y from both sides:

0.95x - x + 1.15y - y = 7
-0.05x + 0.15y = 7 (Equation 3)

Similarly, we can simplify Equation 2 by subtracting x and y from both sides:

1.05x - x + 1.10y - y = 13
0.05x + 0.10y = 13 (Equation 4)

Solving the Equations
Now, we can solve Equations 3 and 4 simultaneously to find the values of x and y.

Multiplying Equation 3 by 20 and Equation 4 by 100 to eliminate decimals:

-1x + 3y = 140 (Equation 5)
5x + 10y = 1300 (Equation 6)

Multiplying Equation 5 by 5 and Equation 6 by 1 to make the coefficients of x equal:

-5x + 15y = 700 (Equation 7)
5x + 10y = 1300 (Equation 6)

Adding Equations 7 and 6:

25y = 2000
y = 80

Substituting the value of y in Equation 5:

-1x + 3(80) = 140
-1x + 240 = 140
-1x = -100
x = 100

Therefore, the cost price of the tea-set is 100 and the cost price of the lemon-set is 80. Thus, option A is correct.

Let cost price of tea-set = ₹ x
and cost price of lemon-set = ₹ y
(i) Loss on tea-set = 
Gain on lemon-set = 
Also,  ...(1)
(ii) Gain on tea-set = 
Gain on lemon-set = 
Also,  ..(2)
Solving (1) and (2), we get ⇒ y = ₹ 80 and x = ₹ 100
