(A) Let the number be $x$.According to the problem,$\frac{2}{3} 	imes \frac{3}{4} 	imes \frac{1}{5} 	imes x = 15$.Simplifying the left side: $\frac{2 	imes 3 	imes 1}{3 	imes 4 	imes 5} 	imes x = 15$.$\frac{6}{60} 	imes x = 15$.$\frac{1}{10} 	imes x = 15$.$x = 15 	imes 10 = 150$.Now,we need to find $30$ per cent of $150$.$30 \% 	ext{ of } 150 = \frac{30}{100} 	imes 150 = 30 	imes 1.5 = 45$.

Two-thirds of three-fourths of one-fifth of a number is $15$. What is $30$ per cent of that number?
