Take the total amt of marks minus the score for science. Since one subject has double the score of the other, one subject will have 1 unit of marks whilst another will have 2 units of marks. Added up together will be 3 units of marks. Total amt of marks minus the score for science will be equal to 3 units. For the subject with lower marks the answer is 1 unit while the subject with higher marks is 2 units. Srry unable to provide picture something wrong wif my phone or the app hope this helps

Answer is 48 cuz after subtracting Science is 144 equaling to 3 units. Math is double of English so English is 1 unit of marks
