Solution(By Examveda Team)

The analysis or grade of a fertilizer refers to the minimum amounts of nitrogen phosphorus in the SSP in the fertilizer.
$$\eqalign{ & {\text{The does of nutrient}} \cr & = \frac{{\left( {{\text{Quantity of fertilizer}} \times {\text{Nutrient content}}} \right)}}{{100}} \cr & {\text{The quantity of fertilizer required}} \cr & = \frac{{\left( {100 \times {\text{Dose of nutrient}}} \right)}}{{{\text{Nutrient contant}}}} \cr} $$
  $$ = $$ 150 kg of SSP is required for application to one acre of rice field.
