Question

Babita bought 2 fans for Rs1200 each. she sold one at a loss of 5% and the other at a profit of 10%. Find Babita's gain or loss percent on the whole dealing.

Answer 1

Case 1:

gain = 10%

Case 1: Sp =?

gain = 10%SP= 100+10 UPoN 100 ×1200

= RS.1320

CASE 2:SP=?LOSS= 5%

SP = 100-5 UPON 100 × 1200

= 1140

Total SP= 1140+1320

Total SP= 1140+1320RS. 2460

TOTAL CP= 1200+1200

TOTAL CP= 1200+1200RS. 2400

PROFIT AS SP>CP 2460>2400PROFIT % = SP-CP. ×100

PROFIT % = SP-CP upon CP × 100

= 2.5% PROFIT ...

Answer 2

Given  C.P of first fan = Rs 1200

He sold the fan at a loss of 5%

⇒ Loss on first fan= 5% of 1200

            

$\tt\large\underline{ \longmapsto \: = \frac{5}{100} \times 1200}$

= Rs 60  

$\tt\large\underline{\longmapsto \: Formula Used}$

S.P of fan = C.P - loss

                

$\tt\large\underline{ \longmapsto \: = 1200 -60}$

=Rs1140

C.P of 2nd fan = Rs 1200

He sold at a profit of 10%

Profit of second fan= 10% of 1200

         

$\tt\large\underline{\longmapsto= \frac{10}{100} \: \times 1200</p><p>}$

=Rs120

S.P of 2nd fan = profit + C.P

                     

$\tt\large\underline{ \longmapsto\: =1200+120= Rs 1320}$

Total cost price of two fans = 1200 + 1200 = Rs 2400

Total S.P of 2 fans = 1320+1140 = Rs 2460

Since S.P > C.P

He got profit on whole

profit = S.P - C.P

          = 2460 - 2400

          = Rs 60

Profit% =

$\tt\large\underline\red{ \frac{profit}{cp} \times 100}$

$\tt\large\underline{=\qquad\longrightarrow\quad\sf \dfrac{\cancel{60}}{\cancel{240}} \times 100}$

             = 2.5% profit on whole
