Question

if 56p (r+6):54p (r+3)=30800:1.find the value of r

Answer 1

56p(r+6):54p(r+3)=30800:1

$=\frac{56p(r+6)}{54p(r+3)}=\frac{30800}{1}$

$=\frac{56(r+6)}{54(r+3)}=\frac{30800}{1}$

now cross multiply

=> 56(r+6)*1=30800*54(r+3)

=> 56(r+6)=1663200(r+3)

=> r+6=29700(r+3)

=> r+6=29700r+89100

=> 6-89100=29700r-r

=> -89094=29699r

=> $\frac{-89094}{29699}=r$

Hence final answer is $r =\frac{-89094}{29699}$
