Question

A dealer bought 18 chairs at Rs 55 per chair. He sold 6 chairs at Rs 50 per chair and the remaining chairs at Rs 65 per chair. Find the gain or loss percentage?

Answer 1

Answer:

Gain % = 9.1%

Step-by-step explanation:

CP = 18 * Rs 55 = Rs 990

SP = 6 * Rs 50 + (18-6) * Rs 65

     = Rs ( 300 + 780)

     = Rs 1080

So, Gain % = ( 1080 - 990) * 100 / 990

                 = 9.1 %

Answer 2

Answer:

$\textbf{\underline{\underline{The Gain \% = 9.5\%}}}$

Step-by-step explanation:

C.P of a toy chair = Rs. 55.

C.P of 18 toy chair = 55 × 18

=> Rs. 1080

S.P of a chair = 50

S.P of twelve chairs = 50 × 12

=> Rs. 600

Remaining chairs = 18 - 12 = 6.

S.P of remaining charis = 65.

S.P of remaining 6 chairs = 65 × 6

=> Rs. 390.

C.P of 18 chairs = Rs.990 + Rs. 390

=> Rs. 1380

⇒ S.P > C.P

Hence, He gains profit.

Amount of the profit = Rs.1380 - Rs.990

=> Rs. 390

We know that :

$\bigstar\; \boxed{\sf \% Profit = \dfrac{Profit}{Cost\;Price}}$

Put the values :

$\longrightarrow \sf \dfrac{390}{1080}\times 100 = 9.5\%\\\\\\\\\textbf{\underline{\underline{Hence,The Gain \% = 9.5\%}}}$
