    Solution

    Let the contribution made by A, B, C, and D be a, b, c, and d, respectively. a+b+c+d = 56 b+c+d = 4.6a Adding a both side a+b+c+d= 5.6a 5.6a= 56 a= 10 lakh Similarly, a+c+d = (11/3) b a+b+c+d = (14/3) b b= 12 lakhs Similarly, 0.4(a+b+d) = c a+b+d = 2.5c a+b+c+d= 3.5c c= 16 lakh Therefore, D = (a+b+c+d)-(a+b+c)                     D = 56 – 38                     D = 18 lakh
