Question

What is the area covered per day of 8 hours by a tractor down four bottom 35 cm plough if the speed of the ploughing is 6km per hour, the time lost in turning is 6%?

(a) 0.39 hectare

(b) 0.67 hectare

(c) 0.23 hectare

(d) 0.40 hectare

This question was addressed to me in an interview for internship.

My query is from Numericals on Mouldboard Plough in division Tillage, Disc Plough & Numericals of Farm Machinery

Answer 1

The correct answer is (d) 0.40 hectare

The best explanation: Area covered/hr = \(\frac{35}{100}*\frac{4}{1}*\frac{6*1000}{1}\) = 8400 m^2

Area to be covered in 8 hours = 8400*8 m^2

Turning loss = \(\frac{6.72*6}{100}\) = 0.40 hectare.
