Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 135 {{1 \over 35}}.

Let the fraction be xy{x \over y}

Now,

⇒ xy164=47516{{x \over y} \over {1\over 64}} = {{4 \over 7} \over {5\over 16}}

⇒ xy×641=47×165{{x \over y} \times {64\over 1}} = {{4 \over 7} \times {16\over 5}}

⇒ xy×641=6435{{x \over y} \times {64\over 1}} = {{64 \over 35}}

⇒ xy=135{x \over y} = {{1 \over 35}}

Hence, the fraction is 135 {{1 \over 35}}
