than wheat by 25%. By what
percentage is wheat cheaper than rice?
​

Answer 1

Answer:

20%

Step-by-step explanation:

Let wheat = x

Find the cost of rice in term of x:

Rice is costlier than wheat by 25%

Rice = x + 0.25x = 1.25x

Find the difference in price in term of x:

Difference = 1.25x - x = 0.25x

Find the percentage of that the wheat is cheaper:

Percentage cheaper = 0.25/1.25 x 100 = 20%

Answer: The wheat is 20% cheaper than the rice.

$\large\mathcal\red{solution}$

let the price of is wheat is =X

therefore the price of Rice is

=X(1+25%)=X(1+25/100)=5x/4

now ....wheat is cheaper than rice by

=(5x/4)-x=x/4

now ....wheat is cheaper than rice by the percentage of ...

$= \frac{ \frac{x}{4} }{ \frac{5x}{4} } \times 100 \\ =20 \: \: percent$
