Answer 2

☆ Given ☆

• A number whose fifth part increased by 30 is equal to its fourth part decreased by 30.

☆ To find ☆

• The number

☆ Step-by-Step-Explaination ☆

Let us take the number as 'n'.

The fifth part of n = ( n ÷ 5 )

The fourth part of n = ( n ÷ 4 )

If we take the question into equation :

( n ÷ 5 ) + 30 = ( n ÷ 5 ) - 30

60 = ( n ÷ 4 ) - ( n ÷ 5 )

LCM = 20

60 = ( 5n - 4n) ÷ 20

60 = ( n ÷ 20 )

1200 = n

Number = 1200.
