$<b><u><i> Solution -</i></u></b>$


# The number = 2400
________________

# 30% of 2400
= 30/100 × 2400
= 30 × 24
= 720
________________

# When 2400 is increased by 30 %
= 2400 + 30% of 2400
= 2400 + 720
= 3120
________________

# 20% of 3120
= 20/100 × 3120
= 2 × 312
= 624
________________

# When 3120 is decreased by 20%
= 3120 - 20% of 3120
= 3120 - 624
= 2496

$\purple{Hence, \: the \: final\: number \: is \: 2496.}$
