A) 30
B) 45
C) 90
D) 150
Correct Answer: B
Solution :
Suppose the number is x, then by question itself. \[x\times \frac{2}{3}\times \frac{3}{4}\times \frac{1}{5}=15,\] \[\Rightarrow \] \[x\times \frac{1}{10}=15\] \[\therefore \] \[x=150\] Now, 30% of \[150=\frac{30\times 150}{100}=45\] So, 30% of the number is 45.You need to login to perform this action.
