Answer 1

Answer:

30

Step-by-step explanation:

Let the science marks be x

we are given that Ram got twice as many marks in English as in science

English marks= 2x

We are also given that the ratio of his marks in English and Maths is 2:3

Math marks = 3x

Now we are given that his total is 180

So, x+2x+3x=180x+2x+3x=180

6x=1806x=180

x=\frac{180}{6}x=

6

180

x=30x=30

Hence the total marks in science is 30
