Find the value of the smallest item of the data

Find the value of the smallest item of the data, if the coefficient of range is 0.6 and the largest value is 60.

Coefficient of range = 0.6, L = 60
Coefficient of Range =L-S/L+S
0.6 = 60-S / 60+S
0.6 (60+S) = 60-S
36 + 0.6 S = 60 - S
1.6S = 24
S = 24/1.6 = 15
Smallest value = 15
