according to given :

amount = 3x

____________________________

amount = principle + simple interest

3x = x + simple interest

si = p × t × r / 100

here ,

si = simple interest

p = principle

t = time given

r = rate of interest

2x = x × 16 × r / 100

2x × 100 = x × 16 × r

r = 2x × 100 / x × 16

r = 12.5 %
