Question

By selling eight dozen lemons ,a vegetable vendor gains the selling price of one dozen lemons . Find his gain per cent

Answer 1

Step-by-step explanation:

Let S.P of 1 dozen lemons be Rs 1

[ 1 Dozen = 12 units]

[8 Dozen = 96]

$\therefore$ S.P of 8 Dozen lemons = Rs 1 × 96 = Rs 96

Gain = S.P of 1 dozen (12 lemons)

Hence,C.P of 8 dozen lemons = S.P - Profit

C.P = Rs 96 - Rs 12 = Rs 84

Profit% = $\dfrac{Profit}{C.P}\: \times 100$

$\implies \: \dfrac{12}{84} \times 100$

$\implies \: \dfrac{100}{7}$

14.28%

Let take S.P of 1 dozen lemons (12) as ₹ 1

So,

So, 8 dozen lemons = 12 × 8 ⇒ 96

=========================================

C.P = S.P - Profit

C.P = ₹ 96 - ₹ 12

C.P = ₹ 84

$\huge{\boxed{\sf{Profit \% \: = \: {\frac{Profit}{C.P}} \: {\times} \: 100}}}$

Profit % = 12 × 100 /84

$\huge{\sf{Profit \% \: = \: 14.28 \%}}$
