Question

The cost of 1 kg of rice is 2 PS3 whole 3 by 14 how many kg of rice can be bought for rupees 25 whole 5 by 7

Answer 1

Given:

The cost of 1 kg of rice is 2 whole 3 by 14 how many kg of rice can be bought for rupees 25 whole 5 by 7?

To find:

how many kg of rice can be bought for rupees 25 whole 5 by 7?

Solution:

We will convert the mixed fractions into simple fractions i.e.,

$2\frac{3}{14} = \frac{(2\times 14) + 3}{14} = \frac{31}{14}$

$25\frac{5}{7} = \frac{(25\times 7) + 5}{7} = \frac{180}{7}$

Now,

For Rs. $\frac{31}{14}$, the quantity of rice that can be bought is 1 kg

For Re. 1, the quantity of rice that can be bought is = $\frac{1}{\frac{31}{14} }\:kg = \frac{14}{31} \:kg$

Then,

For Rs. $\frac{180}{7}$, the quantity of rice that can be bought is,

= $\frac{14}{31} \times \frac{180}{7}$

= $\frac{2 \times 180}{31}$

= $\frac{360}{31}$

= $\bold{11.6\:kg}$

Thus, 11.6 kg rice can be bought for rupees 25 whole 5 by 7.
