Given ratio = \( \Large \frac{7}{2} : \frac{4}{3} : \frac{6}{5} \)
= \( \Large \frac{7}{2} \times 30 : \frac{4}{3} \times 30 : \frac{6}{5} \times 30 \)
= 105 : 40 : 36
Let the investment of Amitabh = 105x
Investment of Brijesh = 40x
Investment of Kamlesh = 36x
Ratio of their investments = [105x X 4 + 150% X 8 of 105x] : (40x X 12) : (36x X 12)
=\( \Large \left( 420x + \frac{150}{100} \times 105x \times 8 \right) \) : (480x) : (432x)
= 35 : 10 : 9
Brijesh's share = \( \Large \left( 21600 \times \frac{10}{35 + 10 + 9} \right) \)
= \( \Large \left( 21600 \times \frac{10}{54} \right) \) = Rs.4000
