SSC CGL General Intelligence and Reasoning 26 Sep 2024
Solution:
Logic: Multiply first and Third Number and add 5 to get Middle number
Check the Logic:
3 — 20 — 5 -> 3×5=15, 15+5=20
4 — 17 — 3 -> 4×3=12, 12+5=17
Apply this logic on the options:
a) 8 — 36 — 11 -> 8×11=88, 88+5=93 Not equal to 36
b) 5 — 28 — 9 -> 5×9=45, 45+5=50 Not equal to 28
c) 9 — 77 — 8 -> 9×8=72, 72+5=77 (Follow the logic)
d) 11 — 28 — 5 -> 11×5=55, 55+5=60 (Not 28)
Correct Option: c) 9 — 77 — 8 is correct Answer
