In a school, the number of girls is 50 more than the number of boys. The total number of students is 1070. Find the number of girls

Solution:

Let the number of boys be x

Then the number of girls be (x + 50)

x + (x + 50) = 1070

2x = 1070 - 50

x = 1020/2

x = 510

Hence, (x + 50) = 560

Thus, the number of girls is 560.
