SSC CPO 2024 PYQ — Question 143

The correct answer is option 2 i.e. 1.

2a + 2b + c = 0

In the above equation, we have given 1 equation and 3 variables.

So, let's assume c = 0

So, 2a + 2b = 0

a = -b

Now put the values in $\frac{4a^2 + 4b^2 + 4c^2}{5c^2 - 8ab}$

= $\frac{4a^2 + 4a^2 + 0}{0 + 8a^2}$

= $\frac{8a^2 }{8a^2}$

= 1
