Answer»

Answer:

  • He scored 73.50 marks in Science.

Step-by-step explanation:

Given that:

  • SACHIN got 60% marks in Maths and 3 marks less than Maths in Science.
  • Total marks are 150.

To Find:

  • How many marks he scored in Science?

Let us ASSUME:

  • Maths marks = 60% of x = 0.6x
  • Science marks = 0.6x - 3

Finding the marks OBTAINED in Science:

Total marks = Maths marks + Science marks

According to the QUESTION.

⇒ 0.6x + 0.6x - 3 = 150

⇒ 2 × 0.6x = 150 + 3

⇒ 0.6x = 153/2

⇒ 0.6x = 76.50

∴ Marks obtained in Science = 0.6x - 3 = 76.50 - 3 = 73.50
