Let the no. of cars be x
According to qn,
x/10 + 1 = x/9
=> (x+10)/10 = x/9
=> 9x + 90 = 10x
=> x = 90
So, total number of cars now = 90+1 = 91
Yellow cars = 90/9 = 10
Hope it helped :-)

supersonu:
prove it
Listen x is total cars
and 1/10 of it is yellow
you have taken x as yellow cars
no
see carefully
my ans is x = 8 and y = 80 so the ratio is 1/10 now add 1 to both x = 9 and y = 81 so now the ratio is 1/9
but x = no of cars and hence this is the answer
idk dude but thnx for your effort
welcome check ans in book plz
