Question

एक दुकानदार ने दो साइकिलें 1100 रु प्रति साइकिल के हिसाब से बेची। एक पर उसे
10% का लाभ एवं दूसरे पर उसे 20% की हानि हुई। बताइए उसे लाभ हुआ कि नहीं?
लाभ या हानि प्रतिशत में ज्ञात कीजिए।​

Answer 1

Answer:

5% हानि ,

Step-by-step explanation:  

पहली साइकिल बेचने पर 10% का लाभ,

$1100\times\dfrac{10}{100}$

= 110रु  

दूसरी साइकिल बेचने पर 20% का नुकसान,

$1100\times\dfrac{20}{100}$

=220रु  

कुल लाभ और हानि,

= कुल लागत मूल्य  -

कुल बिक्री मूल्य ,

$= 2200 - 2090$

= 110

कुल लाभ या हानि,

= $\dfrac{110}{2200}\times100$

= 5% हानि

Answer 2

Answer:

There is a loss of 5%.

Step-by-step explanation:

Given,

The cost price of first cycle = 1100 rupees,

profit% = 10%,

So, the selling price = cost price + 10% of cost price

= 1100 + 10% of 1100

$=1100+\frac{10\times 1100}{100}$

$=1100 +110$

= 1210 rupees,

The cost price of second cycle = 1100 rupees,

Loss% = 20%,

So, the selling price = 1100 - 20% of 1100

$=1100 -\frac{20\times 1100}{100}$

= 1100 - 220

= 880 rupees,

Total selling price = 1210 + 880 = 2090 rupees,

While total cost price = 1100 + 1100 = 2200

Thus,

$\text{ change rate}=\frac{\text{SP-CP}}{CP}\times 100$

$=\frac{2090 - 2200}{2200}\times 100$

$=\frac{-110}{22}$

= -5%

Hence, there is a loss of 5%.
