Text Answer


Nyundo = 1,200
Karai =1,800
Moto =3,000
Ratio of investment;
Nyundo:Karai:Moto
1200:1800:3,000
12:18:30 (divide by 6 to simplify the ratio)
2:3:5
Profit =15000
34% of 15000 = 5,100 (To be shared equally)
Therefore each gets =5,100 ÷ 3 = 1,700
The rest = 100% - 34% = 66%
66% of 15000 = 9,900 (To be shared as per the ratio of investments)
Nyundo gets 210x 9900) + 1,700
1980 + 1,700
=sh.3,680
