Question

In a city, 40% of the houses are white. If there are 200 houses how many
are not white

Answer 1

So 40÷100×200=80

200-80=120

therefore 120 houses are not white

Answer 2

= -40 + 100/100 * 200/1

=60/100 * 200/1

=6/10 * 200/1

=6/1 * 20/1

=120/1

120 houses are not in white House

Long live India
