Answer 1

Answer:

Option B

Explanation:

It is because 30%+10%=40%>30%

Answer 2

option B

Explanation:

let us take

order population be X

&

cultivion y

&

productivity be z

first

X + 3X/10 = 13X/10

and

Y - Y/10 = 9Y/10

X ----->Y

13X/10 -------->13Y/10

but Y is reduced to 9Y/10

so the productivity wanted is 13Z/10 but there is only

but there is only 9Z/10 because Y is directly proportional Z

so increase in population is H

9X/10 + H = 13X/10

H = 4X/10

X is 100%

4X/10 is 40%

increase in productivity is 40% > 30%

so option D
