Explanation:
$$\eqalign{
& {\text{Let Ninad’s investment be Rs}}{\text{.}}x \cr
& {\text{Ratio of capitals}} = \left( {x \times 12} \right):\left( {2x \times 6} \right):\left( {3x \times 4} \right) \cr
& = 12x:12x:12x \cr
& = 1:1:1 \cr
& {\text{Manav’s share}} = {\text{Rs}}{\text{.}}\left( {45000 \times \frac{1}{3}} \right) \cr
& = {\text{Rs}}{\text{.15000}} \cr} $$
