Question
Select the combination of letters that when sequentially
placed in the blanks of the given letter series will complete the series. N _ I _ R N _ _ _ R N NO I _ R N _ I T _Solution
The series is: N O I Q R / N O I R R / N O I S R / N O I T R So, 'O, Q, O, I, R, S, O, R' will complete the given series.Â
