The area of the triangle enclosed by lines y=37x+147, y=779x+147 and y axis is approximately equal to:

0
79
147
750
800

IMO A

explanation:
triangle --> 3 lines defined by
1. y=37x+147
2. y=779x+147
3. y axis ( x = 0)

to find out the point where the first 2 lines intersect the 3rd line, put x = 0 ( because they have to be on the y axis). hence, the meeting points become:
(0,147) , (0,147)

they both are same point. hence, means that there is no triangle.
hence, area = 0 ..i.e. A

The area of the triangle enclosed by lines y=37x+147, y=779x+147 and y axis is approximately equal to...

Just note that y-intercept of both the lines are same. Thus the lines intersect on the y-axis and hence they do not form any triangle with the y-axis.

The correct answer is A.
