hey friend!!!!
Answer 21 min
_____
Explanation:
Area of tap (directly proportional) Work done by pipe.
When diameter is doubled, area will be four times. SO, it will work four times faster.
Hence, required time taken to empty the tank = 84 × 1/4 = 21min.
hope it will help you

let first tank diameter d has volume v
another tank diameter 2d will be vol 4v then
v volume has empty in 84 min
4v volume has empty in 84*4 = 336 min
another tank diameter 2d will be vol 4v then
v volume has empty in 84 min
4v volume has empty in 84*4 = 336 min
