Been at it for hours. Cant think of anything.
That's 1 unit out of 5 units.
So,
Let the selling price of clothing
= ⬛⬛⬛⬛⬛ + $200
After the $200 reduction,
Price = ⬛⬛⬛⬛⬛
After a 20% discount on this price,
Final price = ⬛⬛⬛⬛
Now this price incurs a $50 loss.
So the cost price of the clothing (how much it cost the seller to obtain/procure the clothing)
= ⬛⬛⬛⬛ + $50
Next,
Rearrange the selling price.
Split the $200 into 5 equal parts.
$200 ÷ 5 = $40
It becomes like this :
⬛+$40 ⬛+$40 ⬛+$40 ⬛+$40 ⬛+$40
We get 5 equal parts.
60% = 60/100 = 3/5
That's 3 parts out of 5
So the price after 60% discount means : you have 2 parts left
= ⬛+$40 ⬛+$40
= ⬛⬛+$80
So it equals the cost price.
Since in the earlier steps the cost price was found to be ⬛⬛⬛⬛ + $50 ,
Then we can say :
⬛⬛⬛⬛ + $50
=
⬛⬛+$80
From this we can compare and realise that :
⬛⬛ = $80 - $50 = $30
⬛ = $30 ÷ 2 = $15
Cost price of clothing
= ⬛⬛⬛⬛ + $50
= $15 × 4 + $50
= $60 + $50
= $110
Or
Cost price of clothing
= ⬛⬛ + $80
= $15 × 2 + $80
= $30 + $80
= $110
So if you want to earn 100% profit on the clothing,
100% = 100/100 = 1
The profit is 1 time of the cost price. In other words, the profit amount earned is equal to the cost price.
So we have to add $110. (Answer)
This means the price would have to be :
$110 + $110 = $220
Selling price = ⬛⬛⬛⬛⬛ + $200
= $15 × 5 + $200
= $75 + $200
= $275
Check :
100% - 60% = 40%
40% = 40/100 = 2/5
If sold at a 60% discount , price would be :
$275 × 2/5 = $55 × 2 = $110 (break even) ✔
If price is reduced by $200,
$275 - $200 = $75
100% - 20% = 80%
80% = 80/100 = 4/5
If this is then sold at 20% discount , price would be :
$75 × 4/5 = $15 × 4 = $60
loss incurred = $110 - $60 = $50 ✔
There is another interpretation, which would result in a different answer.
Then $50 = 20% of price (after $200 reduction)
100% of price (after $200 reduction)
= $50 × 5
= $250
Original price = $250 + $200 = $450
60% of this = $450 × 3/5 = $270
So this is the 'break-even' price → the cost price of the clothing.
To earn a 100% profit, I need to earn $270.
Price the clothing is to be sold at
= $270 + $270
= $540
Since the original price is $450
Amount to be added to it
= $540 - $450
= $90
I would say the first interpretation is more likely to be correct though.
