Question

For 500gms = Rs644.00
Each additional 500gms + Rs35.00
How much for 18kg

Answer 1

Answer:

Step-by-step explanation:

500gm=644 Rs

1kg=644+35

1.5 kg=644+35

this is in AP in left

a=0.5 kg,d=0.5 kg An=18 Kg,n=?

18=0.5+(n-1)*0.5

36=1+n-1

n=36

Now in right side

644,(644+35),(644+2*35)

36th term=644+(36-1)*35=644+35*35=644+1225=1869

So 18 Kg for Rs 1869
