Solution
Let the principal ( P ) = Rs x
Amount = A = Rs 3x
Simple interest ( I ) = A - P
I = 3x - x
I = 2x
Rate of interest ( R ) = 40/3 %
Let time = T years
PTR/ 100 = I
T = ( 100 I ) / PR
= ( 100 × 2x ) / ( x × 40/3 )
= ( 100 × 2 × 3 ) / 40
= 15
Therefore ,
T = 15 years

Absolute Value - Example 1
In mathematics, the absolute value or modulus |x| of a real number x is its numerical value without regard to its sign. The absolute value of a number may be thought of as its distance from zero along a number line; this interpretation is analogous to the distance function assigned to a real number in the real number system. For example, the absolute value of ?4 is 4, and the absolute value of 4 is 4, both without regard to sign.
