A starts a business, after 6 months B also join him with Rs.4500 and after 2 months of B’s joining C also join them with Rs.4500. If A gets approx. Rs 4900 out of total annual profit of Rs. 10,000 then find the approximate value of initial investment of A.
Let initial investment of A = x Ratio of profit A : B : C = 12 × x : 6×4500 :4×4500 A :B:C = x : 2250: 1500 Now ATQx/(x+2250+1500) = 4900/10000 solving this we get,x ≈ Rs 3600
