Question

If 6:5=y:20 then what will be the value of y? Select the appropriate alternative answer for the question.
(A) 15
(B) 24
(C) 18
(D) 22.5

Answer 1

$\frac{6}{5} = \frac{y}{20} \\ \\ = 20 \times 6 = 5y \\ \\ = y = \frac{20 \times 6}{5} \\ \\ y = 24$

there option (B) = 24 is correct

Answer 2

Answer:

Value of y = 24

Step-by-step explanation:

As per the question,

We have been provided that 6:5=y:20. That can be written as,

$\frac{6}{5} =\frac{y}{20}$

Now by doing cross multiplication, that is multiply 5 with y and 6 with 20, we get

$\frac{6}{5} =\frac{y}{20}$

5 × y = 20 × 6

⇒5y = 120

⇒y = 120/5

∴ y = 24

Hence, the required value of y is = 24.
