Question

24. Poshiba bought 100 hens for Rs 8000 and sold 20 of these at a gain of 5%. At what gain
percent she must sell the remaining hens so as to gain 20% on the whole?
ANSWERS​

Answer 1

Answer:

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%

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%
