Question

Q. In a clock, the minute-hand crosses the hour-hand in 64 minutes. In one day, the time shown by the clock is how many minutes more or less from the original time?

• A. $47\left(3/11\right)$
• B. $43\left(7/9\right)$
• C. $33\left(7/11\right)$
• D. $43\left(7/11\right)$

Answer 1

The correct option is D $43\left(7/11\right)$

$65\left(5/11\right)–64=1\left(5/11\right)=16/11$
A head or Behind (minutes)
$=\frac{Hours\times 60\times (655/11-F.T.)}{F.T.}$
$=\frac{24\times 60\times 16}{64\times 11}$

$=480/11=43\left(7/11\right)minutes$
