\(n+\frac{2}{5}=5+\frac{7}{5}\)

Quantity A

\(n\)
\(6 \frac{4}{5}\)


A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.



Here,
\(n+\frac{2}{5}=5+\frac{7}{5}\)

or 5n + 2 = 25 + 7

or n = 6, which is < (\(6 \frac{4}{5}\))

Hence QTY A < QTY B

\(n\)
\(6 \frac{4}{5}\)




GIVEN: \(n+\frac{2}{5}=5+\frac{7}{5}\)

Eliminate the factions by multiplying both sides by 5 to get: \(5n+2=25+7\)

Simplify to get: \(5n+2=32\)

Subtract 2 from both sides to get: \(5n=30\)

Solve to get: \(n=6\)

We have:
QUANTITY A: \(6\)
QUANTITY B: \(6 \frac{4}{5}\)

Answer: B

Cheers,
Brent

n+2/5=5+7/5
=> n = 25/5 + 7/5 - 2/5
=> n = (25 + 5) / 5
=> n = 6

Ans: B
