Answer 2

Answer:

Share of A will be 2100

Step-by-step explanation:

As we know that total amount is 7000 and the share of the A will be $\dfrac{3}{7}$ of what B and C receive together

Therefore we would opt for hit and trial method in this question, Assume that B and C together have 5000,  

Therefore 5000$5000\times\dfrac{3}{7}$=2142, i.e., the total will be 7142, i.e., larger than the given value, so our contribution of B and C must be less than 5000, Therefore now we check for 4900

$4900\times\dfrac{3}{7}$=2100, i.e. total=2100+4900=7000 which is satisfied

Hence the contribution of A is 2100
