Answer 1

Question:
Two third of a number is 12 more than two fifth of that number. Find the number.

Solution:
Let the required number be "x".

According to the statement of the question,

( 2 / 3 ) * x = ( 2 / 5 ) * x + 12
=> ( 2x / 5 ) - ( 2x / 3 ) = - 12
=> ( 6x - 10x ) / 15 = - 12
=> - 4x = - 12 * 15
=> - 4x = - 180
[ Remove minus sign from LHS and RHS ]
=> 4x = 180
=> x = 180 / 4
=> x = 45

Therefore,

The required number = x = 45
