A. 405
B. 450
C. 360
D. 400
Answer: Option B
Solution(By Examveda Team)
Marks obtained by D = 320Marks obtained by C
= 320 × $$\frac{125}{100}$$ = 400
Marks obtained by B
= 400 × $$\frac{(100 - 10)}{100}$$ = 360
Marks obtained by A
= 360 × $$\frac{125}{100}$$ = 450
Hence, required marks obtained by A = 450
