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

trasher [3.6K]

Answer:

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

Step-by-step 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

$\sf{profit\% \: = \frac{profit}{cp} \times 100 \%}$

⇒ $\sf{ \frac{120}{1080 } \times 100\%}$

⇒ $\sf{11.11\%}$

Hope I helped!

Best regards!!

What number goes in the box? 2 ^ ( ) = (2^7 ÷ 2^9)^3

navik [9.2K]

Answer:

$x=-6$

Step-by-step explanation:

$(\frac{2^{7}}{2^{9}})^{3} \\(\frac{128}{512})^{3} \\(\frac{1}{4})^{3}\\(\frac{1}{4})*(\frac{1}{4})*(\frac{1}{4})\\\frac{1*1*1}{4*4*4} \\\frac{1^{3} }{4^{3} } \\\frac{1}{64} \\2^{x}=\frac{1}{64}\\log 2^x=log\frac{1}{64}\\x*(log(2))=log\frac{1}{64}\\x=\frac{log\frac{1}{64}}{log(2)} \\x=-6$
