Question

Ganesh sell two chain Rs 800 each gain 20% on one and lose 20%on another.find the gain on loss% in the entire transaction.

Answer 1

Answer:

4% loss

Step-by-step explanation:

Selling Price (S.P) of both the chains = 800/-

Gain on the first chain = 20%

Cost Price (C.P) of the first chain =            

⇒ C.P + (20% of C.P) = 800

⇒ C.P + (20 C.P/100) = 800

⇒ 120 C.P / 100 = 800

⇒ C.P = (800 * 100)/120

=   (2000/3) /-

C.P of the second chain =

⇒ C.P - (20% of C.P) = 800

⇒ C.P - (20 C.P)/100 = 800

⇒ 80 C.P/100 = 800

⇒ C.P = (800*100)/80

= 1000/-

Total C.P of both the chains =

⇒ 2000/3 + 1000

= (5000/3) /-

Total S.P of both the chains =

⇒ 800 + 800

= 1600 /-

Since 5000/3 is greater than 1600, there is a loss incurred. To find the loss:

⇒ 1600/(5000/3) * 100

⇒ (1600 * 3)/5000 * 100

= 96%

So, the loss percentage will be (100-96)% = 4%

Hence, Ganesh incurred a loss of 4%.
