Answer 1

Answer:

Step-by-step explanation:

let the %inc. be X

1000/100 *X= 1420

X=1420/10

X=142

therefore %inc.=142-100

=42 therefore the%inc. in no.of buses =42

Answer 2

percentage increase =42%

Step-by-step explanation:

percentage increase = difference upon initial no. × 100

1420-1000/1000×100

420÷1000×100

420÷10

42%
