Answer 2

Answer:

40

Step-by-step explanation:

Simply you can calculate by multiplying with 2 to make the total marks 100

So,

20 is pass mark out of 50

2*20 is pass mark out of 100(i.e. 2*50)

Hence, 40 is pass marks

Alternatively, you can do by finding the percentage of marks

If 20 is pass marks out of 50

So,

$pass \: \% \: = \frac{pass \: marks}{total \: marks} \times 100 = \frac{20}{50} \times 100 \\ = 40\%$

Now, to find out the passing marks out of 100

$pass \: marks = \frac{pass \: \% \times total \: marks}{100} = \frac{40 \times 100}{100} = 40$
