Option 3 : 5 ∶ 4

Calculation:

Number of students passed in A = 1200 × 22/100

⇒ 264

Number of boys who passed from A = 264 × 5/11

⇒ 120

Number of students passed in D = 1200 × 20/100

⇒ 240

Number of boys who passed from D = 240 × 2/5

⇒ 96

Ratio = 120 : 96

⇒ 5 : 4

∴ Required ratio is 5 : 4

/

⇒ (2 × 5 × 12) ∶ (4 × 2 × 12)

⇒ 5 ∶ 4

∴ Required ratio is 5 : 4
