60, take into consideration his maths and eng marks as x and y. X/3 = y/2 +30. Now, we know that x = 3x (y/2+30) { plz note 3 multiplied by has been written as 3x } We also know that x + y=240 Substitute x = 3x ( y/2 + 30) We get y = 60. Verification: If eng marks is 60 then maths will be 180. 180/3 = 60 which is same as 60/2 +30
