Một cửa hàng bán một chiếc điện thoại được lãi 20% giá bán. Hỏi cửa hàng đó được lãi bao nhiêu phần trăm so với tiền vốn chiếc điện thoại đó ?
Trả lời: So với tiền vốn thì cửa hàng đó được lãi 25%
nếu lãi 20% giá bán thì giá bán sẽ 100%
giá vốn là 100%-20%=80%
lãi số % so với giá vốn là
20 / 80 x100 = 25%
DS 25%
chuẩn 100%
Coi giá bán là 100% thì tiền vốn là :
100% - 20% = 80%
Cửa hàng đó được lãi bao nhiêu phần trăm so với tiền vốn chiếc điện thoại đó là :
20% : 80% = 25%
Số % chỉ giá vốn là:
100%-20%=80%
Số % chỉ tiên lãi theo giá vôn là:
20%:80%=25%
giá vốn so với giá bán thì bằng:
100%-20%=80% ( giá bán )
cửa hàng lãi số % so với giá vốn chiếc điện thoại đó là:
20:80=0,25
0,25=25%
Đ/S:25%

Coi giá bán là 100%. Tiền vốn bằng:
100% - 20% = 80% (giá bán)
Vậy cửa hàng đó được lãi:
20% : 80% = 25% (tiền vốn)
Đáp số: 25% tiền vốn
Đổi : 20% = 1/5
Gía bán : I----I----I----I----I----I
Gía mua : I----I----I----I----I
Vậy 1/4 = 25%
Vậy cửa hàng lãi 25 giá mua
Số tiền lãi tính theo giá bán là
20: (100%-20%) x 100 = 25 %
Đáp số 25 %
