Question

$25$ bags of rice each weighing $40kg$ cost $Rs2750/-$ Find the cost of $35$ bags of wheat if each bag weight $50kg.$

Answer 1

Let the cost of each bag be $x$

According to the question

$25x=2750$

$\Rightarrow x=\frac{2750}{25}$

$\Rightarrow x=110$

Cost of $40$ kg's wheat $=110$

Cost of $1$ kg wheat $=\frac{110}{40}$

$=\frac{11}{4}$

Now, we have to find the cost of $50$ kg

$\therefore$ cost $=50\times$ $\frac{11}{4}$

$=\frac{550}{4}$

$=$Rs. $137.5$

Now, the cost of $35$ bags

$=35\times 137.5$

$=$Rs. $4812.50$.
