Solution

The correct option is A 1
We know that $\sqrt[3]{125} = \sqrt[3]{5 \times 5 \times 5} = 5$ ,
$\sqrt[3]{512} = \sqrt[3]{8 \times 8 \times 8} = 8$ ,
$\sqrt[3]{215} = \sqrt[3]{2 \times 2 \times 2 \times 3 \times 3 \times 3} = 2 \times 3 = 6$ ,
And,
$\sqrt[2]{49} = \sqrt[2]{7 \times 7} = 7$ ,
Now, by putting all the values,
$⟹ \frac{5 + 8}{6 + 7} = \frac{13}{13} = 1$
