and he will take 4 cakes cost 20 rupees

and he will take 100 chocolates cost 50 rupees because one chocolate =1/2......

THEN 30+20+50= 100 RUPEES

Answer 2

Given:

Total amount= 100 rupees

Total Items=100

cost of each chocolate  $x=0.5$ ₹

cost of each biscuit  $y=3$ ₹

cost of each cake $z=3$ ₹

To Find:

Quantity of each item.

Solution:

Framing the above conditions in the equations:

       $0.5x+3y+5z=100$.....................(1)

       $x+y+z=100$...............................(2)

By eliminating $y$ , we get

      $2.5x-2z=200$

By Hit and Trial , we get

       $z=5, x=84$

Put the values of $x$ and $z$   in eq (2), we get

        $y=11$

Hence,  chocolates=84

              biscuits=11

              cakes=5
