उत्तर : 2. "Rs.46400"
व्याख्या :
Answer: B) Rs.46400 Explanation: Interest received by L from K = 8% of half of Rs.40,000 ⇒8100×20000=1600 Amount received by L per annum for being a working partner = 1200 x 12 = Rs.14,400 Let 'A' be the part of remaing profit that 'L' receives as his share. Total income of 'K' = only his share from the reamaing profit = 'A', as both share equally. Given income of L = Twice the income of K --> (1600 + 14400 + A ) = 2A --> A= Rs.16000 Thus total profit = 2A + Rs.14,400= 2(16000) + 14400 = 32000 +14400 = Rs.46,400.
