Question

Y: 5 :: 6:30( Find Y )​

Answer 1

y : 5 = 6 : 30

30/5 = 6

6/6 = 1

1 : 5 = 6 : 30

=> y = 1

Answer 2

Given:

${y:5: \: :6:30} \\product \: of \: means \: = \: product \: of \: extremes \: \\ 5 \: \times \: 6 \: = \: 30 \: \times \: y \\ \implies \: y \: = \: \frac{30}{5 \: \times \: 6} \: = 1 \:$

Hence, the value of $x$ is 1.
