Violet Paint = 100 Litres (30 Litres Blue + 70 Litres Red)
Green Paint = 100 Litres (50 Litres Blue + 50 Litres Yellow)
Total Mixture would be = 200 Litres (80 Litres Blue + 70 Litres Red + 50 Litres Yellow)
Blue paint = x 200 = 80 Litres
Red paint = x 10 =3.5
Let, x days be the original duration of the tour.
Total expenditure on tour = $ 360
Expenditure per day =
Duration of the extended tour = (x + 4) days
Expenditure per day according to the new schedule
Given that daily expenses are cut down by $3 As per the given condition =
or,
or,
or,
Of,
or, x(x + 4) = 480
or, x 2 + 4x = 480
ог, x 2 + 4x - 480 = 0
or, x2 + 24x - 20x - 480 = 0
or, x(x + 24) - 20(x + 24) = 0
x + 24 = 0 or, x - 20 = 0
x = 20 or, x = - 24
Therefore, the original duration of the tour was 20 days
