Given : In a class test having three sections, A scored a total of 51 marks. A's score in the second section was greater than his score in the first section by 7 and lower than his score in the third section by 7.
To Find : How many marks did A score in the second section?
1] 15
3] 24
4] 17
2] 10
Solution:
A score in the second section = M
A's score in the second section was greater than his score in the first section by 7
=> Score in 1st section = M - 7
A's score in the second section was lower than his score in the third section by 7.
=> score in 3rd section = M + 7
Total Score = M + M - 7 + M + 7
= 3M
3M = 51
=> M = 17
A score in the second section = 17
