Solution

(a) If Palak gets x marks, then Abha gets twice the marks as that of Palak, i.e. 2x.

(b) Two times of Abha's marks = 2(2x) = 4x and three times the Palak marks = 3(x) = 3x
Now, two times Abha's marks and three times Palak's marks make 280.
So, the equation formed is 4x + 3x = 280.

(c) Solve the equation for x,
4x+3x=2807x=2807x7=2807x=40
Hence, the solution of the equation is 40.

(d) Marks obtained by Abha are 2x, i.e. 2×40=80.
