A, B and C started a business with a total investment of Rs. 90000. A invests Rs. 6000 more than B and B invests Rs. 3000 less than C. If the total profit at the end of a year is Rs. 8640, Find B's share.
Choose the correct choice from the following:
A) Rs. 2592
B) Rs. 2520
C) Rs. 2880
D) Rs. 3360
E) None of these
Explanation:   Let C's investment = Rs. x   B's investment = Rs. (x - 3000)   A's investment = Rs. (x - 3000 + 6000) = Rs. (x + 3000)   Now, (A + B + C)'s investment = Rs. 90000   =&gt; x + (x - 3000) + (x + 3000) = 90000   =&gt; 3x = 90000   =&gt; x = 30000   Hence, A's investment = Rs. 33000   B's investment = Rs. 27000   C's investment = Rs. 30000   Ratio of the capitals of A, B and C   = 33000 : 27000 : 30000   = 11 : 9 : 10   A's share = Rs. [(9/30) Ã— 8640] = Rs. 2592   Rs. 2592nswer: Option Rs. 2592
