Question

9. In an examination 17% of the students fail. What percentage of students pass? How many
students will pass if 900 students appear in the examinations?
10. If 25% of a number is less than 18% of 650 by 19. find the number​

Answer 1

fail. = 17%

Pass=83%

appeared = 900

pass=900x83/100=747. Ans

25% of a no:=25x/100

18% of 650=650X18/100=117

25x/100-117 = 19

multiply by 100

25x-11700 = 1900

25x=13600

.x = 13600/25=544. Ans

No: 544
