Krishna Kunal if task1 is assigned to P5 or P6 then task2 can be assigned to P2 or P3(2*2). If task1 is assigned to P3 or P4 then task2 has only onle choice left as one from P3 or P4 is already assigned Task1.(2*1). and task3,task4,task5 and task6 has no constraint so 4! ways. so total ways(2*2+2*1)*4!=144

Tanveer Iqbal Ahmed Many students use listen and hear interchangably. However, there is an important difference between them. Listening describes an intentional activity. When you are listening, you are actively trying to hear something.

In contrast, hearing is something that happens without any intentional effort. You can hear something even when you don't want to hear it and don't try to hear it.

The sentences below contain both listen and hear and show the contrast:

I listened outside the door, but I couldn't hear what they were saying inside. [Note that even if you listen, you don't always hear what you are trying to hear.]
His story was so long and boring that I stopped listening, until suddenly I heard my name. [Note that even if you are not listening, you might hear something.]

Deena interned in dual fields of A and E and earned the least. Beena worked in C, earned more than Reena, Cheena and Teena and had the third highest earning. Veena interned in B and earned less than only Pinki, who worked in a dual field. Cheena earned more than Teena but less than Reena. Teena worked in A and earned more than Seema, who interned in a dual field of B and E. Two students had D as their field of work. All eight had different earnings. C and D were not a part of the dual field internships.
