Explanation

Given: The seats allotted for ECE, Mechanical and civil Engineering in a college are in the ratio 3 : 4 : 5. Seats increased by 20%, 35% and 44% respectively Calculation: Let seats be 30x, 40x, and 50x Now, Increased seats of ECE = 30x × 120% ⇒ 36x Increased seats of Mechanical = 40x × 135% ⇒ 54x Increased seats of Civil engineers = 50x × 144% ⇒ 72x Now, New ratio = 36x : 54x : 72x ⇒2:3:4 ∴ The ratio of the increased seats will be 2 : 3 : 4.
