P, Q and R together invested an amount of Rs.

Solution

The given question gives the amount of investment of p, q and R which is P = Rs. 25,000, Q= Rs. 10,000 and R = 20,000. Statement A combined with the question’s information will give us the ratio of their profit i.e. 5 [if gte msEquation 12]>× [if !msEquation]-->[endif]-->1 : 2 [if gte msEquation 12]>× 3 [if !msEquation]-->[endif]--> : 4 [if gte msEquation 12]>× [if !msEquation]-->[endif]-->1; 5:6:4. Now, combine this either with B or C, and profit earned by them can be determined. Therefore, Only A and either B or C together is sufficient.
