Answer 1

$<b>$ hello~

Let the CP of 16 nb be 100.

So, the CP of 1nb = 100/16

And also let the SP of 12nb be 100

So,the SP of 1nb = 100/12

Gain = 100/12 - 100/16

G ==> 400 - 300/48

G = 100/48

G%==> 100/48 ÷ 100/16 × 100

G% ==> 100/3

% ==> 33. 3%

Answer 2

Answer

Let the cost price of 1 notebook be Rs.x

So the cost price of 12 notebooks = 12x

The selling price of 12 notebooks =cost price of 16 notebooks = 16x

So, We get =>

The selling price of 16 notebooks = 16x

Now,

Profit = Selling price - Cost price

=>Profit = 16x - 12x

=>Profit = 4x.

So,Profit % = (profit/c.p.) × 100 %

= [{(4x)×100}/12x]%

=33.33℅.

Hence the profit percentage for selling the notebooks is 33.33℅.

Remember

1)Gain=(S.P.) - (C.P.)

2)Loss=(C.P.) - (S.P.)

3)Gain%=(Gain x 100)/C.P

4)Loss %=(Loss x 100)/C.P

5)SP =[(100 + Gain %)/100]x C.P

6)SP=[(100 - Loss %)/100]x C.P.

7)C.P.=(100x S.P.)/(100 + Gain %)

8) C.P.=(100x S.P.)/(100 - Loss %)
