Question

if a student got 80% of marks in maths and 75% marks in English if each exam is conducted by 50 marks and find the marks of English​

Answer 1

Step-by-step explanation:

$50 \div 100 = 0.5 \\ 0.5 \times 20 = 10 \\ half \: of \: 10 = 5 \\ ans \: is \: 35 \: in \: eng$

marks÷100=0.5

0.5 ×(100-80)=10

75%=50-(10+10÷2)

=35
