Answer 1

Answer:

The marks obtained by Leeta are 15.

Step-by-step explanation:

Let the marks of Lakshmi be 'y'

and the marks obtained by Leeta be 'x'.

According to question-

Marks of Lakshmi = 2 ( Marks of Leeta )

y = 2x

x + y = 45 ... (i)

putting y=2x in equation (i) -

x + 2x = 45

3x = 45

x = 45/3

x = 15.
