Answer 2

Answer:

Ratio of increased seats will be 72:100:135.

Step-by-step explanation:

Given Litreture : Chemistry : Economics= 6:8:9

Increase % of seats in Litreture = 20%

Increase % of seats in Chemistry = 25%

Increase % of seats in Economics = 50%

Let seats in Litreture be 6x

Let seats in Chemistry be 8x

Let seats in Economics bd 9x

After increment,

Number of seats in Litreture =

$6x \times \frac{120}{100} = \frac{720x}{100}$

Number of seats in Chemistry =

$8x \times \frac{125}{100} = \frac{1000x}{100}$

Number of seats in Economics =

$9x \times \frac{150}{100} = \frac{1350x}{100}$

Now ratio of increased seats will be

$\frac{720x}{100} :\frac{1000x}{100}: \frac{1350x}{100} = 72x:100x:135x = 72:100:135$

Required ratio is 72:100:135.
