Question

Refer to the following number and symbol series and answer the question that follows. Counting to be done from left to right only.

(Left) 5 3 % 4 6 & 8 $ 7 * Ω 9 # 1 2 & @ £ (Right)

How many such symbols are there, each of which is immediately preceded by a symbol and also immediately followed by a symbol?

This question was previously asked in
RRB NTPC 2024 Undergraduate CBT 1 Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

One

The correct answer is option 1 i.e. One.

Given series: (Left) 5 3 % 4 6 & 8 $ 7 * Ω 9 # 1 2 & @ £ (Right)

Symbol → Symbol → Symbol

(Left) 5 3 % 4 6 & 8 $ 7 * Ω 9 # 1 2 & @ £ (Right)

Hence, one symbols is there, which is immediately preceded by a symbol and also immediately followed by a symbol.
