Question

Irshad bought 100 hens for 8000and sold 20 of these at a gain of 5percentage. At what gain percent must he sell the remaining hens so as to gain 20percent on the whole?

Answer 1

Answer:

Rs. 7920.

Step-by-step explanation:

Total CP of 100 hens = Rs. 8000

To gain 20% on whole, total SP should be = 8000* 1.2 = Rs. 9600.

CP of 1 hen = 8000/100 = Rs. 80.

CP of 20 hen = 20 * 80 = 1600.

SP to gain 5% = 1600* 1.05 = Rs. 1680.

So SP of remaining hen is = 9600 - 1680 = Rs. 7920

Answer 2

Answer:

PLEASE MARK ME AS BRAINLIEST..

Step-by-step explanation:

Cost of 20 hens = 80×20 = 1600

Sold at 5% gain , selling price = 1•05× 1600

S P = 105×16 =1680

S P rest 80 hens = x× 6400

To take gain of 20% on the whole the S P will be

8000×1•2 = 9600

1680 + 6400x = 9600

6400x = 7920

x =7920/6400 = 792/640 = 1•2375

x% = (1•2375 - 1)×100 = 23•75%
