Hey, here is the answer you are looking for...
Total no. of boys = 640
No. of boys passed = 640 * 60/100 = 384
No. of boys failed = 640- 384 = 256
Total no. of girls = 360
No. of girls passed = 360* 80/100 = 288
No. of girls failed = 360 - 288 = 72
Now, total no. of student failed = 256 + 72 = 328
Hope this helps
