A1, 2 & 3 only

B2 & 3 only ✓ Correct

C2, 3 & 4 only

D1 & 4 only

Correct answer: (B) 2 & 3 only

Explanation

Statements 2 and 3 are correct.

Statement 1: 5% of (25% of 1600) = 5% of 400 = 20, not 50.

Statement 2: 0.15% of (33 1/3% of 10000) = 0.15% of 3333.33 = 5.

Statement 3: rate = 5400 x 100 / (15000 x 3) = 12%.

Statement 4: x/3 = y/4 = z/5 gives x:y:z = 3:4:5, not 2:3:7.
