Question

A man sold two cameras for Rs 6000 each, gaining 20 % on one & losing 20 % on the other. Find the cost price of both the cameras?

Answer 1

Answer:

Let CP of first camera be Rs 100

gain is 20% then SP is 120

when SP is Rs 120 then CP is Rs 100

when SP is Rs 1 then CP is =Rs100/120

when SP is Rs 6000 then CP is =(100/120)×6000

then CP is. = Rs 5000

Let CP of second camera be Rs 100

loss is 20% then SP is Rs 80

when SP is Rs 80 then CP =100

when SP is Rs 1 then CP is =100/80

when SP is Rs 6000 then CP is=(100/80)×6000

then CP is =Rs 7500.

Hope that's OK.
