Answer 1

According to problem:

a=1

d=2

∴Sn=2n[2a+(n−1)d]

          =2n[2+2n−2]

          =n2

∴Mean=nSn=nn2=n

Answer 2

$\huge\mathfrak\purple{Answer} \:$

R's old share= 5/8

S's old share= 3/8

T's share= R's sacrifice + S's sacrifice

= [5/8 * 1/4] + [3/8 * 1/5]

= [5/32] + [3/40]

= 37/160

R's new share= 5/8- 5/32

= 15/32

S's new share= 3/8-3/40

= 12/40

New Profit sharing ratio= 75:48:37
