marks
(b)The equation formed is
(c) The solution of the equation is
(d) Marks obtained by Abha is​

Answer 1

Step-by-step explanation:

Let Abha's marks are X, and Palak's marks are Y.

Given: X= 2Y......... equation (1)

2X + 3Y = 280......... equation (2)

Put eq (1) in (2)

we get

2(2Y) + 3Y = 280

4Y + 3Y = 280

7Y = 280

Y= 280/7

Y= 40 and X= 80

a) If Palak gets x marks, Abha gets

marks 2x

b)The equation formed is X= 2Y......... equation (1)

2X + 3Y = 280......... equation (2)

c) The solution of the equation is X= 80 and Y= 40.

d) Marks obtained by Abha is 80.
