Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 2 : 3 : 4.

Given:

The seats allotted for ECE, mechanical and civil engineering in a college are in the ratio 3 : 4 : 5

There is a proposal to increase the seats by 20%, 35% and 44%

Calculations:

Let the seats allotted for ECE, mechanical and civil engineering be 3x, 4x and 5x

Seats for ECE = 3x × 120% = 3.6x

Seats for mechanical = 4x × 135% = 5.4x

Seats for civil engineering = 5x × 144% = 7.2x

Required new ratio = 3.6x : 5.4x : 7.2x

= 2 : 3 : 4
