Question

in a examination 35%of the students passed and 455 failed .how .many students appeared for the examination



​

Answer 1

Answer:

700 students

Step-by-step explanation:

Let total number of students appeared in the examination be = x

Percentage of students passed=35%

Therefore,

Number of students passed = 35% of x

= 35/100×x

= 7/20×x

= 7x/20

Number of students that failed =455

Therefore,

Total number of students that appeared -

x =7x/20+455

x =7x+(455×20)/20

= 20x=7x+9100

= 20x-7x = 9100

= 13x = 9100

= x=9100/13

= x =700.

Therefore, 700 students appeared for the examination.
