Answer 1

Answer:

PLZ MARK AS BRAINLIEST !

Step-by-step explanation:

i) Loss = Rs 5

Profit gained by selling one pen = Re. 1

Profit gained by selling 45 pens = Rs 45

45 + x = - 5

x = - 50

So, a loss of Rs 50 has occurred while selling pencils.

No. of Pencils sold = 50 / 0.40

                             = 125

She sold 125 pencils in this period.

(ii) Profit Or Loss Incurred = 0

70 pens were sold, so profit gained = Rs 70

Cost Price Of Pencils = 70 - 0 = Rs 70

No. of pencils sold = 70 / 0.40 = 175

Therefore,

She Sold 175 pencils in the next month.

Answer 2

Answer:

$\qquad \:\boxed{\begin{aligned}& \qquad \:\bf \: (i) \: \: \: 125\qquad \: \\ \\& \qquad \:\bf \: (ii) \: \: \:175 \end{aligned}} \qquad$

Step-by-step explanation:

Given that,

A shopkeeper earns a profit of 1 rupees by selling one pen and incurs a loss of 40 paise per pencil.

(i) In a particular month she incurs a loss of 5 rupees in this period she sold 45 pens, how many pencils did she sell in this period.

Let we assume that shopkeeper sold x pencils in this period.

So,

Profit earned on selling 45 pens = Rs 45

Loss on selling x pencils = Rs 0.4 x

So, According to statement,

$\sf \: 45 - 0.4x = - 5$

$\sf \: - 0.4x = - 5 - 45$

$\sf \: - 0.4x = - 50$

$\sf \: 0.4x = 50$

$\sf\implies \: x = 125$

So, it means shopkeeper sold 125 pencils in this period.

(ii) In the next month, she earns neither profit nor loss if she sold 70 pens, how many pencils did she sell

Let assume that shopkeeper sold x pencils during this period.

So,

Profit earned on selling 70 pens = Rs 70

Loss on selling x pencils = Rs 0.4 x

So, According to statement,

$\sf \: 70 - 0.4x = 0$

$\sf \: - 0.4x = - 70$

$\sf \: 0.4x = 70$

$\bf\implies \: x = 175$

So, shopkeeper had to sold 175 pencils in this period.
