Choose the correct choice from the following options.
A) 2150
B) 2200
C) 2100
D) 2250
E) 2300
Ratio of investments Kala : Sudha : Githa =&gt; 18000 : 24000 : 20000 =&gt; 9 : 12 : 10.   Investment x time.   Kala = 9 x 12 = 108.   Sudha = 12 x 12 = 144.   Githa = 10 x 9 = 180.   Or Kala : Sudha : Githa =&gt; 6 : 8 : 5.   Let shares of Kala, Sudha and Githa be = 6a : 8a : 5a.   Difference between the profits received by Kala and Sudha   6a – 8a = 2a = 840 or a = 420.   Githa = 5a = 5 x 420 = Rs.2100.   Option 2100
