Question

Saloni Rai got 30 marks in mathematics. If it is 75% off the full marks, how much is the full marks?

Answer 1

Answer:

40 marks

Step-by-step explanation:

Let the full marks in the test be x

Saloni Rai got 75 % of the full marks

=> He got 75 % of x

But it is given that he scored 30 marks

=> 75 % of x = 30

=> ( 75 / 100 ) * x = 30

=> x = ( 30 ) * ( 100 / 75 )

=> x = ( 3000 / 75 )

=> x = 40

Hence the full marks is 40

Answer 2

Answer:

Let the full marks in the test be x

Saloni Rai got 75 % of the full marks

=> He got 75 % of x

But it is given that he scored 30 marks, so

Step-by-step explanation:75 % of x = 30  

=  75/100 x= 30

= x = 30  100/75

= x =3000/75

= x = 40

Hence the full marks is 40
