Answer 1

Hey dude here is yours ans••••

Step-by-step explanation:

Let her saving at day one be t1=10

And on second day be t2=11

And on third day be t3=12.

# a=10, d= t2 - t1 = 1,tn=31

# tn= a+(n-1)xd

t31= 10+(31-1)x1

= 10+30x1

= 10+30

t31 = 40 .

Therefore,on 31st December 2016 sanika total savings will be RS=40.
