Question : 10 of 40

Marks: +1, -0

If

√{0.06 ×0.6 ×x} = 0.006× 0.6 × √y

then find

x /y

.

$36 /1000$
0.06
$3 /50$
$9 /{25,000 }$
None of these

Solution:

√{0.06 ×0.6 ×x} = 0.006× 0.6 × √y

√x/√y={0.006×0.6}/√{0.06×0.6}

Squaring both sides

x/y={0.006×0.6×0.006×0.6}/ {0.06×0.6}

x/y=36/{1,00,000}=9/{25,000}
