19) 0.3 Re.

20) 552.63 approx.

Step-by-step explanation:

AngelSis this question is basically related with Profit and loss So, We have to use some concepts related to it.

19) Given:

Cost Price(c.p) of 4 lemon = 1 Re.

Profit percentage(p.p)= 20 %

To Find:

Sell price(s.p)

Solution:

We can solve it by just using a formula

 \sf s.p = \:  c.p + \dfrac{p.p\:  \times c.p}{100}

As c.p of 4 lemons = 1 Re

So, s.p of 1 lemons = 1/4 Re = 0.25 Re

Now, Putting the values in Formula

 \sf s.p = \:  c.p + \dfrac{p.p\:  \times c.p}{100}

 = 0.25 +  \dfrac{20  \times 0.25}{100}

 = 0.25 +  \dfrac{0.25}{5}

 = 0.25 + 0.05

 = 0.30

Hence, The required s.p is 0.3 Re

20)Given:

S.P = Rs. 500

Loss percentage(l.p)= 5%

To find:

A sell Price which can give 5% profit.

Solution:

Answering process will be held in two step.

1st) for c.p

2nd) To find

Let, cosider the c.p be 100x

As you know c.p - l.p= s.p +

 \therefore \: (100x - 5 \: \% \: of \: 100x)= 500

100x - 5x = 500

95x = 500

x =  \dfrac{500}{95}  \implies \:  \dfrac{100}{19}

Again,

New s.p = c.p + p.p

 =  100x + 5\% \: of \: 100x

 = 100x + 5x

 = 105x

 = 105  \times  \dfrac{100}{19}

 = 552.63

Therefore, The required s.p is Rs 552.63 approximate.

Remember Again,

Sell Price = s.p

Cost price = c.p

Loss percentage = l.p

Profit percentage = p.p
