Question

The line passing through the point (3,2) and one is parallel to x^2-2y^2=0 and other is perpandiculsr to y=3 find the join equation

​

Answer 1

Case 1:

Tractors = 6

Days = 4

Area ploughed by one tractor = 120 hec

Area ploughed by all 6 tractors in a day = 6 x 120

= 720 hec

So, area ploughed by the tractors in 4 days = 720 x 4 = 2880 hec

So, total area of the field = 2880 hec

Case 2:

Tractors = 6 - 2 = 4

Days = 5

Area ploughed by one tractor = ?

Area of the field = 2880 hec

So,

2880 = Area ploughed by one tractor x Total = tractors x Total days

2880 = Area ploughed by one tractor x 4 x 5

Area ploughed by one tractor = 2880/20

So, area ploughed by one tractor = 144 hec
