Answer 1

Answer:

Amit Obtained 81 marks in Science is answer of the question

Step-by-step explanation:

Amit scored 73 marks out of 150 in Mathematics

i.e. (73÷150)×100 percent

=48.66 %

Let Percentage of marks scored in science be A

Overall percentage is ( 56 + 48.66 +  A)÷3 = 54   percent

                                    ⇒( 56 + 48.66 +  A) = 54×3           ( Transfer from LHS to RHS)

                                    ⇒ 104.66 + A           =162

                                    ⇒A                            = 162 - 104.66

                                     ⇒ A                          = 57.34 %

Now  (X÷150)×100 = 57.34

⇒X = (57.34 ÷ 100)×150

⇒X = 86.01 ≅ 86 marks
