Shweta cut a cake on her birthday. She gave half of the cake to her three friends, kept ¼ of it for her sister and the rest for herself. Later, two more friends came and she divided her part in three equal pieces and they ate together.
How much part of the original cake could she eat ?

Correct option is D

Let the original size of the cake as 'x'.

Two more friends came, and she divided her part in three equal pieces, so each person ate

of the cake.
Therefore, Shweta could eat x/12 of the original cake, which is equivalent to 1/12 of the original cake.
So the answer is (d) 1/12.
