Answer 2

Answer :-

The percentage of students who failed is 30%.

Step-by-step explanation :-

To Find,

• Find the percentage of students who failed the examination.

Solution,

Given that,

• 1050 students out of 1500 students passed the exam.

Therefore,

According the question,

Number of students who failed,

Total number of students - Number of students passed

= 1500 - 1050

= 450 ★

Hence, number of students failed is 450.

Now, percentage of students who failed,

= { Number of students failed / Total surface of students } × 100

= { 450 / 1500 } × 100

= 0.3 × 100

= 30% ★

Hence, percentage of students who failed is 30%.
