Answer 2

Answer: 3.  10500

Step-by-step explanation:

A invest 10000 for 12 month that is 120000 and also invest 5000  extra after three month. remaining 9 month investment 5000× 9 =  45000

A total invest 120000+45000= 165000

B invest  10000 for 12 month that is 120000 and also invest 5000  extra after 6  month.    remaining 6 month investment is 50000 × 6 = 30000 THEN

B total invest 120000+30000= 150000

C invest  10000 for 12 month that is 120000 and also invest 5000  extra after 8  month.    remaining 4 month investment is 50000 × 4 = 20000 THEN

C total invest 120000+20000= 140000

D invest  10000 for 12 month that is 120000 and also invest 5000  extra after 10  month.    remaining 6 month investment is 50000 × 2 = 10000 THEN

D total invest 120000+10000= 130000

RATIO of investment is ABCD is 165000 : 150000 : 140000 : 130000

                                                            33:30:28:26

total  profit is 43875

share of C is 28/117  ×  43875 = 10500
