Answer»

ANSWER:

Time taken = 5years

option (C)

Step-by-step EXPLANATION:

PRINCIPAL = Rs9534

Rate of interest = 4%

Amount = Rs11442

so,SI= A-P

SI = Rs11442-Rs9534

SI = Rs1908

Time taken = 100×SI/P×R

= 100×1908/9535×4

= 190800/38140

= 5.0026

Answer» Answer:- $\mathfrak\red{<klux>PROFIT</klux>}$ = ${\boxed{\mathfrak\green{<klux>RS</klux>.288}}}$ $\mathfrak\red{Profit\%}$ = ${\boxed{\mathfrak\green{32\%}}}$ Step-by-step explanation: GIVEN:- CP = 18 dozen @ Rs.50 per dozen. SP = 18 dozen @ Rs. 5.5 each. Loss%/Profit% = ? A shopkeeper purchased 18 dozen eggs @ Rs.50 per dozen. $\Rightarrow\sf CP = Number \times Rate \\\\\Rightarrow\sf CP =Rs. (18 \times 50)$ $\Rightarrow{\boxed{\mathfrak\red{CP = Rs.900 }}}$ $\rule{300}{1}$ The shopkeeper sold 18 dozen of eggs @ Rs. 5.5 each. ${\boxed{\sf{1\:dozen = 12 }}}$ $\Rightarrow\sf Number\:of\:eggs = 18 \times 12$ $\Rightarrow\mathfrak\green {Number\:of\:eggs}$ = ${\boxed{\mathfrak\green{ 216 }}}$ $\rule{100}{2}$ $\Rightarrow\sf SP = Number \times Rate \\\\\Rightarrow\sf SP = Rs.( 216 \times 5.5) \\\\\Rightarrow{\boxed{\mathfrak\red{SP = Rs.1188 }}}$ As, 1188 > 900 . So, SP > CP We know that, if SP > CP, then it BECOMES profit. $\Rightarrow\sf Profit = SP - CP \\\\\Rightarrow\sf Profit = Rs.(1188 - 900)$ $\Rightarrow{\boxed{\mathfrak\green{Profit = Rs.288 }}}$ $\rule{300}{1}$ $\bigstar{\boxed{\sf\purple{Profit\%=\dfrac{Profit}{CP} \times 100 }}}$ $\bold{* Substituting\: values:-}$ $\Rightarrow\sf Profit\% =\dfrac{288}{9\cancel{00}}\times 1\cancel{00} \\\\\Rightarrow\sf Profit\% =\cancel{\dfrac{288}{9}} \\\\\Rightarrow\huge{\boxed{\mathfrak\green{Profit\% = 32\%}}}$ $\therefore\bold{Profit\:will\:be\:Rs.288}$ $\therefore\bold{Profit\%\: will \: be \: 32\%}$

A shopkeeper purchased 18 dozen of eggs at rate of rupees 50 per dozen he sold eggs at rate of rupees 5.50each find his profit or loss and profit or loss percent

Answer»

Answer:-

$\mathfrak\red{<klux>PROFIT</klux>}$ = ${\boxed{\mathfrak\green{<klux>RS</klux>.288}}}$

$\mathfrak\red{Profit\%}$ = ${\boxed{\mathfrak\green{32\%}}}$

Step-by-step explanation:

GIVEN:-

CP = 18 dozen @ Rs.50 per dozen.
SP = 18 dozen @ Rs. 5.5 each.

Loss%/Profit% = ?

A shopkeeper purchased 18 dozen eggs @ Rs.50 per dozen.

$\Rightarrow\sf CP = Number \times Rate \\\\\Rightarrow\sf CP =Rs. (18 \times 50)$

$\Rightarrow{\boxed{\mathfrak\red{CP = Rs.900 }}}$

$\rule{300}{1}$

The shopkeeper sold 18 dozen of eggs @ Rs. 5.5 each.

${\boxed{\sf{1\:dozen = 12 }}}$

$\Rightarrow\sf Number\:of\:eggs = 18 \times 12$

$\Rightarrow\mathfrak\green {Number\:of\:eggs}$ = ${\boxed{\mathfrak\green{ 216 }}}$

$\rule{100}{2}$

$\Rightarrow\sf SP = Number \times Rate \\\\\Rightarrow\sf SP = Rs.( 216 \times 5.5) \\\\\Rightarrow{\boxed{\mathfrak\red{SP = Rs.1188 }}}$

As, 1188 > 900 . So, SP > CP

We know that, if SP > CP, then it BECOMES profit.

$\Rightarrow\sf Profit = SP - CP \\\\\Rightarrow\sf Profit = Rs.(1188 - 900)$

$\Rightarrow{\boxed{\mathfrak\green{Profit = Rs.288 }}}$

$\rule{300}{1}$

$\bigstar{\boxed{\sf\purple{Profit\%=\dfrac{Profit}{CP} \times 100 }}}$

$\bold{* Substituting\: values:-}$

$\Rightarrow\sf Profit\% =\dfrac{288}{9\cancel{00}}\times 1\cancel{00} \\\\\Rightarrow\sf Profit\% =\cancel{\dfrac{288}{9}} \\\\\Rightarrow\huge{\boxed{\mathfrak\green{Profit\% = 32\%}}}$

$\therefore\bold{Profit\:will\:be\:Rs.288}$

$\therefore\bold{Profit\%\: will \: be \: 32\%}$

Find the angle which is 72 degrees of its complement

Answer»

We have to find the ANGLE which is 72 DEGREES of its complement

• COMPLEMENTARY angles are the angles WHOSE sum is 90 degree.

A+ B= 90

A= 72 degree

72+B= 90

B= 18 degree

Hence the complementary angle of 72 degree is 18 degree.

Thanks.
