Answer 1

Answer:

Revised ratio = 2: 3 : 4

Step-by-step explanation:

vacancies for engineers, diploma and artisans were in the ratio of 5:7:8 and it was decided to increase by 40,50 and 75% . what will be the revised ratio​

engineers : diploma :  artisans ::: 5 : 7 : 8

Let say engineers Vacancies = 5x

Diploma Vacancies = 7x

Artisan Vacancies = 8x

Engineers Vacancies increased by 40%

5x + (40/100)5x =  7x

Diploma Vacancies increased by 50%

7x + (50/100)7x =  10.5x

Artisan Vacancies increased by 75%

8x + (75/100)8x =  14x

New Ration   7x : 10.5x  : 14x

Multiplying by 2

14x : 21x : 28x

Dividing by 7x

2 : 3 : 4

Revised ratio = 2: 3 : 4
