Bu'aa Akka Dhibbarraatti Shallaguu.

*Bu'aan daldala tokko keessatti gatiin gurgurtaa(g.g) gatii bittaa (g.b) yoo caaleedha.

Bu'aa= g.g - g.b

%Bu'aa = (g.g - g.b)/(g.b) x 100%

%Bu'aa = (Bu'aa)/(g.b) x 100%

Bu'aa= (%Bu'aa x g.b)/100%

g.g =g.b + (%Bu'aa x g.b)/100%

Fkn 1. Tolaan Lukkuu tokkoo Qr.350'n bitee deebisee Qr.420tti yoo gurgurate,

a. Bu'aa Qr.meeqa buufate?

b. Dhibbantaa meeqaa bu'aa argate?

Deebii 1a.

Ken. Barb. Fur.

g.b=350 Bu'aa? Bu'aa= g.g - g.b

g.g=420 =420-350=70

Bu'aa Qr.70 argate.

Deebii 1b.

Ken. Barb.

g.b=350 Bu'aa?

g.g=420

Furmaata.

%Bu'aa = (g.g - g.b)/(g.b) x 100%

%Bu'aa = (420 - 350)/(350) x 100%

=(70)/(350) x 100%

=(70x100%)/(350)

=(7000%)/350=20%

Bu'aan isaa dhibbantaan 20% ta'a.

2. Qaadiin raadiyoo qr.180n bituun 25% bu'aa buufachuun yoo gurgurate.

a. Bu'aa Qr.meeqa buufate?

b. Raadiyoo kana qr.meeqatti gurgurate?

Deebii 2a.

Kennama Barb.

g.b=180 Bu'aa?

%Bu'aa=25%

Furmaata.

Bu'aa= (%Bu'aa x g.b)/100%

=(25% x 180)/100%

=(4500%)/100%= 45

Bu'aa Qr.45 argate.

Deebii 2b.

Kennama Barb.

g.b=180 g.g?

%Bu'aa=25%

Furmaata.

g.g =g.b + (%Bu'aa x g.b)/100%

g.g =180 + (25% x 180)/100%

g.g =180 + (4500%)/100%

g.g=180 + 4500/100

g.g=180 + 45

g.g=225

Raadiyoo kana qr.225tti gurgurate.
