Answer» Correct Answer - Option 3 : 4 : 5 : 5 Given: Seats of IT, mechanical and civil in a college are in ratio 4 : 4 : 5 Calculation: Let the seats of IT, mechanical and civil be 4x, 4x and 5x After increment seats of IT will be = 4x × 120/100 = 4.8x After increment seats of Mechanical will be = 4x × 150/100 = 6x After increment seats of civil will be = 5x × 120/100 = 6x ⇒ required ratio = 4.8x : 6x : 6x ⇒ After solving ratio = 4 : 5 : 5 |
