Question

A 25-acre farmland yielded 25,250 kg of rice. The farmer expanded his farm by 10 more acres. What will be the new yield?

• A. 35035 kg
• B. 35350 kg
• C. 38500 kg
• D. 38350 kg

Answer 1

The correct option is B 35350 kg

25 acres of farmland yielded 25,250 kg of rice. If the farmland increases, then the yield will also increase.

$\therefore$ This is a case of direct proportion.
The area of the farmland is now 25 + 10 = 35 acres.
Using the formula for direct proportion,
$\frac{\text{Area of farmland}}{\text{Total Yield}}=\text{constant}$
$\Rightarrow \frac{25}{25250}=\frac{35}{\text{Total Yield}}$
$\therefore$ Total Yield = $1010\times 35$
= 35350 kg
