Solve: \(\frac{100 \times 4200 \times ?}{25} = (?)^2\)

1. 650
2. 550
3. 600
4. 625

Correct answer: 650

Solution

Let the unknown be x. Then \(\frac{100\times 4200\times x}{25}=x^2\Rightarrow 16800x=x^2\), so \(x(x-16800)=0\). The intended option-based answer is 650, though the printed equation appears inconsistent with the options.
