A, B, C rent a pasture. A puts 10 oxen for 7 months, B puts 12 oxen for 5 months and C puts 15 oxen for 3 months for grazing. If the rent of the pasture is Tk. 175, how much must C pay as his share of rent?
A Tk. 45
B Tk. 50
C Tk. 55
D Tk. 60
Solution
Correct Answer: Option A
A : B : C = (10 x 7) : (12 x 5) : (15 x 3)
= 70 : 60 : 45
= 14 : 12 : 9
Therefore, C's rent = Tk. (175 x 9/35) = Tk. 45
