Answer 2

The value of $(30-20)$ is $580$

Step-by-step explanation:

Given,

If $10-5=45$ and $20-10=190$ then $30-20=?$

First parts,

$10-5$

$=(10\times5)-5$

$=45$

Second parts,

$20-10$

$=(20\times10)-10$

$=190$

Similarly,

$30-20$

$=(30\times20)-20$

$=580$

∴ The value of $(30-20)$ is $580$
