Answer 2

Given : Cost of 12½ kg of rice is Rs. 60

To find : The cost of 10 kg rice.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the cost of 10 kg rice)

Now,

Rs. 60 is the cost of = 12½ kg rice = $\frac{12 \times 2 + 1}{2} = \frac{25}{2} = 12.5 \: kg$

Now, we will be using general arithmetic method.

So,

Cost of 12.5 kg rice = Rs. 60

Cost of 1 kg rice = Rs. $\frac{60}{12.5}$

Cost of 10 kg rice = Rs. $\frac{60 \times 10}{12.5}$

Cost of 10 kg rice = Rs. 48

(This will be considered as the final result.)

Hence, the cost of 10kg rice is Rs. 48
