Question

15:270::13:? (reasoning )

208/275/169/144​

Answer 1

Answer:

By taking a close look at all the numbers in the sequence it is clear that all the given numbers are perfect squares of numbers.

15×15=225

14×14=196

13×13=169

12×12=144

9×9=81 but the number given in the series is 80

So 80 is the wrong term from the series.

Option A is the correct answer.
