A. 296694
B. 296695
C. 296696
D. 296697

Answer 1

Hint: In order to solve this problem subtract the number of girls given from the total number of the children. Consider the variables and then put the value of the number of girls participated. Doing this you will get the right answer.

Complete step-by-step answer:
Let us consider,
"x" be the total number of girls participating.
"y" be the total number of boys participating.

From given, we have,
x + y = 732680

As the number of girls given is 4,35,986.
Then we can say: 4,35,986 + y = 732680

So, y = 732680 − 4,35,986
y = 296694

Therefore, a total of 296694 boys participated in this event.
Hence, the correct option is A.

Note: To solve this problem we need to understand that if we have given the total number of children and then also we have been told the number of girls in it so the rest of the number is boys. Therefore on subtracting the number of girls with the total number of children you will get the total number of boys participated.
