# In an examination 35% of the students passed and 455 students failed

In an examination 35% of the students passed and 455 students failed. How many students appeared for the examination?

(a) 490

(b) 700

(c) 845

(d) 1300

**Answer: (b) 700**

**Solution:-**Let the number of the students who appeared for the examination be X

In an examination 35% of the students passed.

Then, failed students = 100 – 35 = 65%

455 students failed,

Then, X x 65/100 = 455

13 X/20 = 455

13 X = 455 x 20

13 X = 9100

X = 9100/13

X = 700

Then, the number of the students who appeared for the examination is 700.

Hence, the correct answer is option (b) 700.
