Question

John bought three thermos flask at a total of st 1080 he later sold at 400 each what was his percentage ​

Answer 1

`\boxed{ \bold{ \boxed{ \sf {11.11\%}}}}`

Explanation:

Given,

Cost price of three thermos flask = 1080

Selling price of each thermos flask = 400

Finding the selling price of three thermos flask

Since, the cost of 3 thermos flask is more than that of 1 thermos flask. So, the cost of 1 thermos flask is multiplied by 3 ( i.e 400 × 3 = 1200 )

Here, the selling price is greater than cost price.

So, there is profit.

And we know that,

`\sf{profit = sp \: - \: cp}`

⇒
`\sf{1200 - 1080}`

⇒
`\sf{120}`

Profit amount = 120

Finding the profit percentage

`\sf{profit\% \: = (profit)/(cp) * 100 \%}`

⇒
`\sf{ (120)/(1080 ) * 100\%}`

⇒
`\sf{11.11\%}`

Hope I helped!
