Question

If a remote train fare increases by 25%, the passenger population decreases by 20% The percentage of income increases or decreases​

Answer 1

Answer:

let earlier no. of passenger be x

and cost of fair be y

then total income x×y

now increase fair =y+y×25%=1.25y

new no. of passenger =x-x×20%=.80y

so new total income=1.25y×.8x

=1.000 xy=xy

so % increases or decrease=0%
