Question : 32 of 160

Marks: +1, -0

If 1.5x = 0.04y, then the valueof

({y-x}/{y+x})

is :

${730}/{77}$
${73}/{77}$
${7.3}/{77}$
${703}/{77}$
None of these

Solution:

1.5 x = 0.04 y
⇒

x/y

=

{0.04}/{1.5}

=

4/{150}

=

2/{75}

∴ Expression =

{y-x}/{y+x}

=

{1-x/y}/{1+x/y}

=

{1-2/{75}}/{1+2/{75}}

=

{{75-2}/{75}}{{75+2}/{75}}

=

{73}/{75}

×

{75}/{77}

=

{73}/{77}
