Correct Answer - Option 5 : If statement l and ll together not sufficient
Calculation:
Let be assume investment of A, B and C is X, Y, and Z
⇒ X + Y + Z = 21400
From statement l
⇒ B's profit is 11200 and if the investment of B is (Y - 3000) and investment of C is (Z - 3000) then profit of B is 15200
⇒ Hence we cannot get the annual profit from statement l alone
From statement ll
⇒ B invested 8400 rupees but we cannot define the investment of A and C so we cannot get annual profit
⇒ Hence from statement ll alone not sufficient to answer the question
Both statement l and ll together not sufficient to answer the question
∴ The required result will be "If both of them together are not sufficient".
For annual profit we must require the time and investment of regarding persons.
