Why were the ryots Relerctant to grow Indigo

Posted by Ankit Ankit 6 years, 4 months ago

CBSE > Class 08 > Social Science

1 answers

Sia ? 6 years, 4 months ago

Under the ryots system, the planters forced the ryots to sign a contract an agreement.
Those who signed the contract got cash advances from the planters at low rates of interest to produce indigo.
But the loan committed the ryot to cultivate indigo at least 25% of the area under his holding.
The planter provided the seed and the drill, while the cultivators prepared the soil, sowed the seed and looked after the crop.
When the crop was delivered to the planter after the harvest, a new loan was given to the ryot, and the cycle started all over again.
The price they got for the indigo they produced was very low and the cycle of loans never ended.

Gaurav Seth 6 years, 4 months ago

Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed!

So, integers can be negative {-1, -2,-3, -4, -5, ... }, positive {1, 2, 3, 4, 5, ... }, or zero {0}

We can put that all together like this:

Integers = { ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }

Steps of Construction

Draw LD = 5 cm.
With L as centre and radius LG = 6 cm, draw an arc.
With D as centre and radius DG = 6 cm, draw another arc to intersect the arc of step 2 at G.
With L as centre and radius LO = 7.5 cm, draw an arc.
With D as centre and radius DO = 10 cm, draw another arc to intersect the arc of step 4 at O.
Join DG, GO, OL, LG and DO.

Then GOLD is the required quadrilateral.
