Question

Answer 1

Answer:

Given:-

Rabin bought 5 apples for ₹30 and sold each apple at ₹8, how much percent did he gain?

To Find:-

Percent of gain.

Note:-

●》Here, First we will take S.P. in 5 apples amount from 1 apple amount; C.P. is the amount at which things are brought and S.P. is the amount at which things are sold.

●》For calculating Gain Percentage, Gain needs to be there i.e. Gain = S.P. - C.P.

●》Gain Percentage ( % ) = $\frac{Gain}{C.P.} × 100$

Solution:-

[ Note first point ]

$\huge\red{C.P. \ \ for \ \ 5 \ \ apples = ₹30}$

$\huge\red{\ \ S.P. \ \ for \ \ 1 \ \ apple = ₹8, For \ \ 5 \ \ apples = ?}$

☆ We know that~

▪︎$S.P. \ \ for \ \ 1 \ \ apple = ₹8$

▪︎$S.P. \ \ for \ \ 5 \ \ apples = ₹8 × 5$

▪︎$S.P. \ \ for \ \ 5 \ \ apples = ₹40$

$\huge\pink{S.P. \ \ for \ \ 5 \ \ apples = ₹40}$

____________________________________________________

[ Now, we will calculate Gain ]

$\huge\red{C.P. = ₹30, S.P. = ₹40}$

$\huge\red{\ \ \ \ Gain = ?}$

☆ According to note second point~

▪︎$Gain = S.P. - C.P.$

▪︎$Gain = ₹40 - ₹30$

▪︎$Gain = ₹10$

$\huge\pink{Gain = ₹10}$

___________________________________________________

[ Now, we will calculate Gain Percentage ( % ) ]

$\huge\red{Gain = ₹10, C.P. = ₹30}$

$\huge\red{\ \ \ \ Gain Percentage = ?}$

☆ According to note third point~

▪︎$Gain \ \ Percentage = \frac{Gain}{C.P.} × 100$

▪︎$Gain \ \ Percentage = \frac{₹10}{₹30} × 100$

▪︎$Gain \ \ Percentage = \frac{₹1,000}{₹30}$

☆ After reducing~

▪︎$Gain \ \ Percentage = \frac{100}{3}$

▪︎$Gain = \frac{100}{3}$%

☆ Mixed fraction~

▪︎$Gain \ \ Percentage = 33 \ \frac{1}{3}$

▪︎$Gain = 33 \ \frac{1}{3}$ %

$\huge\green{Gain = \frac{100}{3}}$% $\huge\green{ \ \ or \ \ 33 \ \frac{1}{3}}$ %

Answer:-

Hence, Rabin Gain = $\frac{100}{3}$% or $33 \ \frac{1}{3}$ %.
