Question

To plough 800 bighas of land 4 tractors take 4 days. At this rate, how many days will be take by 3 tractors to plough 1200 bighas of land

Answer 1

Answer:

ans :-. 24

Step-by-step explanation:

in 4 days 800 bighas of land is cultivated ..

so in one day 800/4 = 200 bighas are cultivated...

here 4 tractors cultivate 200 bighas in 1 day...

1 tractor. = 200/4 = 50

according to the question :-

1200 bighas land in 3 days..

Tractors. = ??

no.of.tractors = total land / no.of.land cultivated by 1 tractor..

= 1200/50

= 24. tractors...

Answer 2

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
