Solution

Step $1 .$ Finding the change in price
Given that the price of onion changes from $₹ 10$ to $₹ 6$
Change in price $=$ Original price $-$ New price
$= 10 - 6$
$= ₹ 4$
Step $2 .$ Finding the decrease in percentage of the price
Decrease percentage of the price $=$ $(\frac{D e c r e a s e i n p r i c e}{O r i g i n a l p r i c e} \times 100) %$
$= (\frac{4}{10} \times 100) %$
$= 40 %$
Hence the decrease percentage in the price of onion is $40 %$
