Then, price of set of shirt and trouser = Rs. 300.

After giving 30% discount on the set,

Selling Price = 300 - 30% of 300 = 210.

Total Discount on Set = 90.

And Discount on shirt is 20% alone,

SP of shirt alone = 100 - 40% of 100 = 60.

Rs. 40 is the discount on shirt then Rs. 50 must be the discount on the trouser.

So, discount on trouser = ^{(50*100)}/_{200} = 25%.

CP = x(let)

Profit % = CP

Or, [^{(39-x)}/_{x}] * 100 = x [% profit= ^{(SP-CP)}/_{CP}]

3900-100x = x^{2}

X^{2}+100-3900 = 0

X = 30. (we cannot take negative value of x)

1000==25%↑==> 1250 **[person calculating profit on the CP]**

1000 ==33.33%↑==> 1333.33 **[The person calculating his profit on SP: 25% of SP = 33.33% of CP]**

The difference turned out to be = 83.33. this has occured when we have assumed the CP as 1000. But, we are given difference of Rs. 100.

So, on comparing,

83.33 = 1000

1 = [^{1000}/_{83.33}]

100 = [^{1000}/_{83.33}] *100 = Rs. 1200.

^{(40 *500)}/

_{100}= Rs. 200.

Two successive discount on 500,

= 30% of 500 + 10% of (500 - 30% of 500).

= 150 + 10% of 350.

= 150 + 35 = Rs. 185.

Difference in Discount = 200 - 185 = Rs. 15

**While buying,**

He buys 1100 gram instead of 1000gram.

Suppose he bought 1100 grams for Rs. 1000.

**While selling,**

He sells only 900 grams when he takes the money for 1 kg.

Now, according to the problem,

he sells at a 8% profit (20% markup, 10% discount).

Hence, his selling price is Rs. 1080 for 900 grams.

Now,

1100grams for Rs. 1000

Hence, 1188 grams for Rs. 1080

Selling: 900 grams for Rs. 1080.

Hence, % profit = 288/900 = 32%.

(using goods left by goods sold formula).

Let his CP = Rs. 100.

Marked Price = 100 + 25% of 100 = 125.

Now, discount = ^{25}/_{2}% on MP.

So, SP = 125 - (^{25}/_{2})% of 125 = Rs. 109.375.

%Gain = 9.375%.

**Alternatively** use graphic change method:

100(CP)==25% Up==>125(MP)==12.5%down ==>109.375.

%Profit = 9.375%.
