A) 2 : 5
B) 4 : 5
C) 3 : 2
D) 5 : 2
Correct Answer: B
Solution :
[b] Let the 3rd number be x. Then, 1st number = 120% of x \[=\left( \frac{120}{100}\times x \right)=\frac{6x}{5}\] 2nd number = 150% of x \[=\left( \frac{150}{100}\times x \right)=\frac{3x}{2}\] \[\therefore \] Ratio of these numbers \[=\frac{6x}{5}:\frac{3x}{2}=12:15=4:5\] |
