Answer 1

Answer:

answr is 10 option 2.

since difference ia 126 =15%

then 924= 924/126×100 = 110

profit here 110-100 = 10 %

p =10

Answer 2

ANSWER IS 10%

CONCEPT USED -

1) Profit percent is calculated on cp.

$P/cp ×100$

eg If the CP is 10 Rs and i got profit of 5 Rs then profit is 50 %

2)

$100\% \: p = cp$

- If the profit is 10 Rs and CP also 10Rs so P = 100% .ie 100% profit gives us CP.

Now in the above question the CP is same but SP is changing

$1st \: Selling \: price = 924$

$2nd \: Selling \: price= 1050$

Difference :-

$SP2- SP1= 126$

The question says the profit is 15% extra from the previous one :

we sold for 126 Rs more ie we got a profit of 126 Rs more than the previous one.

So this 126 Rs profit give us 15% extra profit.So if we find 100% profit and that will be CP.

OR You can put values in this formula

$P/cp×100=profit \%$

Using 1st method

$15\%=126$

$100\%= 126/15×100$

$= 840 = cp$

For profit%

$924-840=84= profit$

$84/840×100$

$=10\% =profit%$

So profit = 10%
