Question

the answer and the step how to do​

Answer 1

Step-by-step explanation:

SP of the camera = Rs 1080

Let Rs x be the CP.

Gain = Rs (1/8)x…….(i)

Also gain = Rs (1080 – x) …….(ii)

From (i) and (ii), we have:

From (i) and (ii), we have:

∴ 1/8 x=1080 – x

⇒ x = 8640 – 8x

⇒ x + 8x = 8640

⇒ 9x = 8640

⇒ x = 960

∴ CP = Rs 960

Gain RS. 960/8 = 120

Gain %= (12/960*100)% =12 (1/2 )%( in

whole no.)
