Answer 1

$\boxed {\underline {\mathbb {FINAL\:ANSWER:-}}}$

$\boxed{d)10minute}$

$\boxed {\underline {\mathbb {GIVEN:-}}}$

pipe A can fill an empty tank in 15 minutes

pipe B in 30 minutes

$\boxed {\underline {\mathbb {TO\:FIND:-}}}$

how minutes they take to fill the tank when both pipes are opened together

$\boxed {\underline {\mathbb {SOLUTION:-}}}$

Time taken by pipe A is 15 min

Time taken by pipe B is 30 min

Therefore time taken by both pipe A and B opened  together –

Time = \farc{AB}{A+B}

Time =\frac{15\times 30}{15+30}

Time = \farc{450}{45}

Time =10 \  min  

Hence time taken together by both pipes A and B $\boxed{\implied 10 \ min}$
