Step 1: Chinky’s answers b d d c b d a b a b
Step 2: Compare with others Rahul: b d d c b d a b a b ✔️ (exact match)
Sastry (final key): b d d c b d a c a b Only Q8 differs ⇒ So if Chinky had two jigris (Sastry and Rahul), for Q8:
Sastry has 'c', Rahul has 'b' ⇒ not identical ⇒ Chinky leaves it blank
But Chinky wrote 'b' ⇒ copied from Rahul So consistent.
Hence, jigris are Sastry and Rahul.
