Question

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

Answer 1

Solution:

Let the number of boys be x

Then the number of girls be (x + 50)

The linear equation formed is

x + (x + 50) = 1070

2x = 1070 - 50

x = 1020/2

x = 510

Hence, (x + 50) = 560

Thus, the number of girls is 560.

✦ Try This: In a school, the number of girls is 41 more than the number of boys. The total number of students is 973. Find the number of girls.

Let the number of boys be x

Then the number of girls be (x + 41)

A/Q

x + (x + 41) = 973

2x = 973 - 41

x = 932/2

x = 466

Hence, (x + 41) = 507

Thus, the number of girls
