Best answer

Total investment = Rs 360000 

Profit earned = 12% 

∴ Total profit = 12% of 360000 

= 12/100 x 360000 

= Rs 43200 

Proportion of investment = 3 : 4 : 7 : 6

Let the investment of Jaya, Seema, 

Nikhil and Neelesh be Rs 3x, Rs 4x, Rs 7x and Rs 6x respectively. 

3x + 4x + 7x + 6x = 360000 

∴ 20x = 360000 

∴ x = 360000/20

= 18000 

∴ Jaya’s investment = 3x = 3 x 18000 = Rs 54000 

Also, profit made by them is Rs 43200 

∴ 3x + 4x + 7x + 6x = 43200 

∴ 20x = 43200 

∴ x = 43200/20

= 2160 

∴ Nikhil’s profit = 7x = 7 x 2160 = Rs 15120 

∴ Jaya’s share in the capital was Rs 54000 and the profit made by Nikhil was Rs 15120.
