a man sold two cameras at rupees 924 each on one he gains 20% and an another he lost 20% How much does the gain or loss on the whole
Answers
Case (i)
SP =Rs 924 Gain 10%
let CP= Rs 100
SP= 100+10=110
when SP is Rs 110, CP= 100
when SP is Re. 1 , CP= 100/110
When SP is Rs 924, CP= (110/100)×924
=Rs1016.4
Case(ii)
SP=924 Loss= 10%
let CP= Rs100
SP=Rs 90
when SP is Rs 90, CP = Rs 100
when SP is Rs 924, CP= Rs (100/90)×924
=Rs 9240/9
=1026.67
Now SP of Both the cameras = 2x924=Rs1848
CP of both the cameras = Rs (1016.40+1026.67)=Rs 2043.07
since CP>SP, Loss= 2043.07-1848=195.07

Answer: HI GUYS SO THE ANSWER IS
4% loss
Step-by-step explanation: let cp be x
120/100* x = 924
x= 924 *100/120
x=770/-
condition for loss=
let cp = y
80/100*x=924
y= 924*100/80
y=1155/-
total sp= 924+924= 1848
total cp = 770= 1155 = 1925
loss = 1925 - 1848
=77/-
L%= 77/1925*100
L%= 4%
