Expert Answer
Let x be number of girls and y be number of boys.
If total number of students is 10 , then we have
............................(1)If number of girls is 4 more than number of boys , then
x- y = 4 .................... (2)
By adding , equations (1) and (2) , we get , 2 x = 14 or x = 7
From equation(1) , y = 10 -x = 10-7 = 3
Hence 7 girls and 3 boys attended the quiz program
