Question

$A$, $B$, $C$ 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 Rs. $175$, how much must $C$ pay as his share of rent?

• A. Rs. $45$
• B. Rs. $50$
• C. Rs. $55$
• D. Rs. $60$

Answer 1

The correct option is A Rs. $45$

$A:B:C=(10\times 7):(12\times 5):(15\times 3)=70:60:45=14:12:9$.
$\therefore$ $C$'s rent $=$ Rs. $(175\times \frac{9}{35})=$ Rs. $45$.
