Question

Make an equation, for the marks secured by Rushik is 80 but he has secured 8 marks less than double the marks secured by the his friend Sathvik.​

Answer 1

Answer:

(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,
