we assume that
rahim's score in exam =x
karim's score in exam =x+15
madan's score in exam = x-10
there total score =110
x+x+15+x-10 = 110
3x + 5 =110
3x =110-5=105
x = 105/3 =35
rahim score is 35
rahim's score in exam =x
karim's score in exam =x+15
madan's score in exam = x-10
there total score =110
x+x+15+x-10 = 110
3x + 5 =110
3x =110-5=105
x = 105/3 =35
rahim score is 35
