D. 342

​

Answer 1

Answer:

B)375

Step-by-step explanation:

Balu scored 45% marks and failed by 18 marks

pass mark of the class = 45%of total mark + 18

Radhika scored 54% marks and get 27 marks more than the passing marks

pass mark of the class = 54% of total mark - 27

total marks = x

Here passing marks equal. So,

45 % of x+ 18 = 54 % of x-27

18 + 27 = (54 — 45) % of x

45 = 9 % of x

x = 45*(100/9) = 500

Mohan's mark = 75/100* 500 = 375

hope it helps you...
