Cost of $5kg$ of wheat is $Rs30.50$
(a) What will be the cost of $8kg$ of wheat?
(b) What quantity of wheat can be purchased in $Rs61$.

Answer 1

Cost of $5kg$, wheat is $=30.50Rs$

Cost of $1kg$ wheat is $=\frac{30.50}{5}$

Cost of $8kg$ wheat is $=\frac{30.50}{500}\times 8$

$=\frac{61\times 8}{10}$

$=\frac{488}{10}$

$=48.80Rs$

$30.50Rs.$ is Cost of $=5kg$ wheat

$1Rs.$ o\is cost of $=\frac{5}{30.50}$

then,

$xkg$ wheat can be buy in $61Rs$.

$=\frac{500}{30.50}\times 61$

$=\frac{50}{305}\times 61$

$=10kg$
