7/50 : 9/82 :: 13/170 : ?
Answer & explanation
Correct answer: option 4
7/50 : 9/82 :: 13/170 : ?
The logic;
7/50
7/(\( {7 }^{ 2} \) + 1 )
49 +1= 50
9/82
9/(\( {9}^{ 2} \) + 1 )
81 +1= 82
13/170
13/(\( {13}^{ 2} \) + 1 )
169 +1= 170
And,
15/226
15/(\( {15}^{ 2} \) + 1 )
225 +1= 226
Thus, 15/226 is correct.
