Three numbers are such that the second is 150% of the first, and the third is 80% of the second. What is the ratio of the first to the third?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 5:6.
Let first number = 100
Second = 150% of 100 = 150
Third = 80% of 150 = 120
Ratio of first : third = 100 : 120 = 5 : 6
