128 bananas

Step-by-step explanation:

Given,

The original number of bananas = 160,

Decreases percentage = 20%,

So, the decrease in the number of bananas = 20% of 160

$=\frac{20\times 160}{100}$

$=\frac{3200}{100}$

= 32,

Hence, final number of bananas = original bananas - decrease in bananas

= 160 - 32

= 128
