B2 & 3 only

C1 & 3 only ✓ Correct

D1, 2 & 4 only

Correct answer: (C) 1 & 3 only

Explanation

Statements 1 and 3 are correct.

Statement 1 : 5 : 4 = 5/4 = 1.25 = 125%, which is true.

Statement 3 : half of 1% = 0.5% = 0.5/100 = 0.005, which is true.

Statement 2 fails : 3.5 = 350%, not 250%.

Statement 4 fails : 63% of 25/7 = 0.63 x 3.571 = 2.25, not 22.5.
