5.	6. A fruit vendor buys fruits from the fruit market at wholesale prices and sells them at his shop atretail prices. He operates his shop 30 days a month, as a rule. He buys in multiples of 100 fruitsand sells them in multiples of a dozen fruits. He purchases mangoes for ' 425 per hundred andsells at 65 per dozen, he buys apples at 150 per hundred and sells at 30 per dozen, he buyswatermelons (always of equal size) at 1800 per hundred and sells at 360 per dozen. Which ofthe three fruits yields him the maximum percentage profit?(a) Mangoes(b) Apples(c) Watermelons(d) Both (b) and (c)
Answer» ANSWER: For mangoes, purchase Cost of 100= 425 = 4.25/pc Sell cost of 12 = 65 = 5.4/pc So profit is 5.4-4.25 = ₹1.15 Profit percentage = 1.15/4.25 × 100 = 27.06% For APPLES, purchase Cost of 100= 150 = 1.5/pc Sell cost of 12 = 30 = 2.5/pc So, similarly, profit percentage = (2.5-1.5)/1.5 × 100 = 66.67% For watermelon, purchase Cost of 100= 1800 = 18/pc Sell cost of 12= 360 = 30/pc So profit percentage = (30-18)/18 × 100 = 66.67% Hence, OPTION (d) is correct.

6. A fruit vendor buys fruits from the fruit market at wholesale prices and sells them at his shop atretail prices. He operates his shop 30 days a month, as a rule. He buys in multiples of 100 fruitsand sells them in multiples of a dozen fruits. He purchases mangoes for ' 425 per hundred andsells at 65 per dozen, he buys apples at 150 per hundred and sells at 30 per dozen, he buyswatermelons (always of equal size) at 1800 per hundred and sells at 360 per dozen. Which ofthe three fruits yields him the maximum percentage profit?(a) Mangoes(b) Apples(c) Watermelons(d) Both (b) and (c)

Answer»

ANSWER:

For mangoes, purchase Cost of 100= 425 = 4.25/pc

Sell cost of 12 = 65 = 5.4/pc

So profit is 5.4-4.25 = ₹1.15

Profit percentage = 1.15/4.25 × 100 = 27.06%

For APPLES, purchase Cost of 100= 150 = 1.5/pc

Sell cost of 12 = 30 = 2.5/pc

So, similarly, profit percentage = (2.5-1.5)/1.5 × 100 = 66.67%

For watermelon, purchase Cost of 100= 1800 = 18/pc

Sell cost of 12= 360 = 30/pc

So profit percentage = (30-18)/18 × 100 = 66.67%

Hence, OPTION (d) is correct.

Find the value of dy/dx , if x= 2 cos square t, y= 2 sin square t

Answer»

ANSWER :–

$\\ \longrightarrow \: \: \large { \red{ \boxed{ \bold{ \dfrac{dy}{dx} = - <klux>1</klux> }}}} \\$

EXPLANATION :–

GIVEN :–

• ${ \bold{ x = <klux>2</klux> \: {cos}^{2}t }}$ and ${ \bold{ y = 2 \: {sin}^{2}t }} \\$

TO FIND :–

• The value of ${ \bold{ \: \dfrac{dy}{dx} = ? }} \\$

SOLUTION :–

• We know that –

$\\ \implies { \pink{ \boxed{ \bold{ \dfrac{dy}{dx} = \dfrac{ \dfrac{dy}{dt} }{ \dfrac{dx}{dt} } }}}} \\$

• So , let's find ${ \bold{ \: \dfrac{dy}{dt} \: \: - }} \\$

$\\ { \bold{ \implies y = 2 \: {sin}^{2}t }}$

• Now DIFFERENTIATE with respect to 't' –

$\\ { \bold{ \implies \frac{dy}{dt} = 2 \times \: 2{sin}t \times cost }}$

$\\ { \bold{ \implies \frac{dy}{dx} = 4 \: {sin}t . cost \: \: \: \: - - - -eq.(1) }}$

$\\ { \bold{ \implies x = 2 \: {cos}^{2}t }}$

• Now Differentiate with respect to 't' –

$\\ { \bold{ \implies \frac{dx}{dt} =2 \times 2 \: {cos}t \times ( - sint ) }}$

$\\ { \bold{ \implies \frac{dx}{dt} =4\: {cos}t \times ( - sint ) \: \: \: - - - - eq.(2) }}$

• Now divided eq.(1) and eq.(2) –

$\\ \because \: \: \: { \bold{ \dfrac{dy}{dx} = \dfrac{ \dfrac{dy}{dt} }{ \dfrac{dx}{dt} } }} \\$

• Put the values from eq.(1) and eq.(2) –

$\\ \implies \: \: \: { \bold{ \dfrac{dy}{dx} = \dfrac{ 4 sin(t) cos(t) }{4 cos(t) [ - sin(t) ] } }} \\$

$\\ \implies \: \: \large { \red{ \boxed{ \bold{ \dfrac{dy}{dx} = - 1 }}}} \\$

$\\ \: \: \large { \bold{ \underline{Used \: \: formula} : - }} \\$

$\\ \: \: { \bold{(1) \: \: \frac{d( {x}^{n} )}{dx} = n {x}^{n - 1} }} \\$

$\\ \: \: { \bold{(2) \: \: \frac{d[sin( \theta)]}{dx} = cos( \theta) }} \\$

$\\ \: \: { \bold{(3) \: \: \frac{d[cos( \theta)]}{dx} = - \: sin( \theta) }} \\$
