Answer:
Dinesh scored 58 marks more than Sunil
Step-by-step explanation:
Let Sunil marks be x and Manish marks be y and Dinesh marks be z
1st equation
x = 0.6y
2nd equation
y = 0.7z
Manish scored 70 marks
therefore, y = 70
in 1st equation
x = 0.6 * 70
x = 42
in 2nd equation,
70 = 0.7 z
z = 70/0.7
z = 100
Sunil scored 42 and Dinesh scored 100
Therefore, Dinesh scored 100 - 42 = 58 marks more than Sunil
