In a cricket tournament 16 school terms participated. A sum of Rs.8000 is to be awarded among themselves as prize money.

Solution

Tn=a+(n1)d

275=a+(161)d

275=a+15d...(1)

Sn=n2[2a+(n1)d]

S16=162[2a+(161)d]

8000=8[2a+15d]

1000=2a+15d...(2)

(2)-(1) gives:

(2a+15d)(a+15d)=1000275

a=725

Therefore Rs.725 is received by the first place team.
