Answer 1

SOLUTION

COMPLETE QUESTION

The average marks scored by a student in 10 tests was 32. How much must the student score in the next test so as to increase the average marks by 4

EVALUATION

Here it is given that the average marks scored by a student in 10 tests was 32.

So total marks scored by a student in 10 tests

= 32 × 10

= 320

Now we have to find the score in the next test so as to increase the average marks by 4

In that case total number of tests

= 10 + 1

= 11

Now new average = 32 + 4 = 36

So total marks scored by a student in 11 tests

= 36 × 11

= 396

Hence the required score in the next test

= 396 - 320

= 76

FINAL ANSWER

Hence the student score 76 in the next test so as to increase the average marks by 4
