their own vehicles ?

Answer 1

Dear Student,

◆ Answer -

Percent of clerks and teachers not having vehicles are 77.78 %.

● Explanation -

Let x be some random variable such that total no of clerks is 5x and total teachers is 4x. Total no of clerks and teachers is 5x+4x = 9x.

No of clerks having vehicle are 20% of 5x = 5x × 20/100 = x. No of teachers having vehicles is 25% of 4x = 4x × 25/100 = x. Total no of clerks and teachers having vehicles is x+x = 2x.

No of clerks and teachers not having vehicles is 9x-2x = 7x. Percent of clerks and teachers not having vehicles are 7x/9x × 100 = 77.78 %.

Thanks dear. Hope this helps you...
