Question

What will come in the place of '?' in the following equation, if '+' and '−' are interchanged and '×' and '+' are interchanged? 
7 + 4 × 18 − 3 × 2 = ?

This question was previously asked in
SSC CGL 2024 (Tier-I) Previous Year Paper (17-Sep-2024) (Shift 3)
The correct answer is

24

The question text as printed is logically inconsistent. It asks for plus and minus to be interchanged AND multiplication and plus to be interchanged simultaneously, assigning two different swap targets to plus. No interpretation produces 24. The stem itself needs editing, which is outside option/solution scope - admin correction required.
