Question

JK 9 is related to MJ -7 in a certain way. In the same way, PQ 4 is related to SP -12. To which of the following is QR 13 related, following the same logic?

This question was previously asked in
RRB NTPC 2025 Under Graduate CBT 1 Question Paper PDF (20-Jun-2026) (Shift 3)
The correct answer is

TQ -3

Checking JK 9 to MJ -7: J(+3)=M, K(-1)=J, number changes by -16.

Checking PQ 4 to SP -12: P(+3)=S, Q(-1)=P, number changes by -16, matching the same pattern.

Applying to QR 13: Q(+3)=T, R(-1)=Q, number changes to \(13-16=-3\).

Hence, QR 13 is related to TQ -3.
