Question

Drops of water fall at a uniform rate from a Kalash (pot) over the Shivling in the Shiva temple. If $9$ drops fall in $10$ sec, how many drops fall in $15$sec?

• A. $14$
• B. $12$
• C. $13$
• D. $16$

Answer 1

The correct option is C $13$

Since one drop will mark the beginning of the time period i.e. 10 seconds
$\therefore$ $8$ drops take $10$ second
$\therefore$ in $15$ second, $12$ drops will fall
Again $1$ drop will mark the beginning
$\therefore$ total drops that will fall are $=12+1=13$ drops
