Question

Shikha secured 7386 and 76 and 75 marks in four test what is the least number of points we can secure in her next test if she is to have an average of 80 ​

Answer 1

Answer:

90

Step-by-step explanation:

1st marks........ 73

2nd marks.....86

3rd marks..... 76

4th marks..... 75

sum....... 310

average (of 5 test marks) = 80

so, the sum of 5 tests = 80*5 = 400

sum of 5 tests - sum of 4 marks

400-310 = 90 = next test's marks
