If digit \(h\) is the hundredths digit in the decimal \(d=0.2h6,\) what is the value of \(d,\) rounded to the nearest tenth?
(1) \(d < \dfrac14\)
(2) \(h < 5\)
Answer:
D
Source: Official Guide
Given: Digit h is the hundredths digit in the decimal d=0.2h6
Target question: What is the value of d, rounded to the nearest TENTH?
Statement 1: d < 1/4
In other words, 0.2h6 < 0.25
This means h = 0, 1, 2, 3 or 4
If h = 0, 1, 2, 3 or 4, then
0.2h6 (aka d) rounded to the nearest TENTH is 0.2
Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: h < 5
This means h = 0, 1, 2, 3 or 4
If h = 0, 1, 2, 3 or 4, then
0.2h6 (aka d) rounded to the nearest TENTH is 0.2
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
