(A) 7413
(B) 4312
(C) 9876
(D) 6500
Correct Option is: A
Let investment of M is X + 385
Let investment of N is X
Profit earned of M&N is,
M/N=(X+385)*5 /x *9——-> (1)
Profit of M =65 +profit of N
Total profit = 1350=65 +profit of N + profit of N
Profit of N =Rs.642.5
Profit of M =65 +642.5= Rs.707.5
Profit ratio of both = 707.5 :642.5
=283 :257——-> (2)
From 1& 2, 283 /257 =(x + 385) *5/(x*9)
X =392.01
Total investment =(392+385)*5+(392*9)
=Rs.7413
