Step-by-step explanation:
let the weight of fertilizer be x
It is given that combined weight is 29 kg
Weight of soil was 2 kg more than three times the weight of fertilizer
i.e.
soil weight is 3x+2
Also weight of compost was half the weight of fertilizer
i.e. compost weight =
And combined weight
x+3x+2+
=29
x=6 kg
Difference in weight of soil and compost
