the answer is 21 because they have asked "the sum of numbers that belong to 1 figure only." which means we have to add all the numbers that belong to any one of the following :-circlesquaretrianglehexagonTotal of all the numbers that belong to hexagon = 21So, the answer is 21.If you still don't understand, read my comment once again.
