Question

Find the value of y if 4 : y :: 8 : 10​

Answer 1

y = 5

Step-by-step explanation:

if 4 : y :: 8 : 10

4 × 10 = 8y

y = 40/8

y = 5

Answer 2

Answer :-

$4:y$ $::$ $8:10$

$\frac{4}{y} =\frac{8}{10}$

$=>4$ × $10=8y$

$=>40=8y$

$=>40\div8=y$

$=>5=y$

Verification :-

$LHS=\frac{4}{y}$

$=\frac{4}{5}$

$=\frac{4}{5}$ × $\frac{2}{2}$

$=\frac{8}{10}$

$RHS=\frac{8}{10}$

$LHS=RHS$ $hence,$ $verified.$

Thus,

$The$ $value$ $of$ $y$ $is$ $5.$
