Question
There are 1400 students in a college, 25% of those wear hats and 2/7 of those wearing hats are boys. How many girls in the college wear hats?
Solution
Step 1: Find the number of students who wear hats. 25% of 1400 students wear hats. So, 1400 * 25/100 = 350 students wear hats.
Step 2: Find the number of boys who wear hats. 2/7 of those wearing hats are boys. So, 350 * 2/7 = 100 boys wear hats.
Step 3: Find the number of girls who wear hats. The number of girls who wear hats is the total number of students who wear hats minus the number of boys who wear hats. So, 350 - 100 = 250 girls wear hats.
So, 250 girls in the college wear hats.
