Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 1125.

⇒(1.7100×800)=13.6\Rightarrow \left( \frac{1.7}{100} \times 800 \right) = 13.6 \\[5pt]

⇒(2.5100)=0.025\Rightarrow \left( \frac{2.5}{100} \right) = 0.025

⇒13.6×0.025×a=382.5⇒0.34a=382.5⇒a=382.50.34=1125\Rightarrow 13.6 \times 0.025 \times a = 382.5 \\[5pt] \Rightarrow 0.34a = 382.5 \\[5pt] \Rightarrow a = \frac{382.5}{0.34} = 1125
