Team Careers360 · Accepted Answer

Correct Answer: 49 : 81 : 64

Solution : Given: $\frac{J}{4}=\frac{K}{5}=\frac{L}{3}$
Let, $\frac{J}{4}=\frac{K}{5}=\frac{L}{3}=x$
So, $J=4x,K=5x$ and $L=3x$
Now, $(L + J)^2:(J +K)^2:(K +L)^2$
= $(3x+4x)^2:(4x+5x)^2:(5x+3x)^2$
= $49x^2:81x^2:64x^2$
= 49 : 81 : 64
Hence, the correct answer is 49 : 81 : 64.
