An empty backet being filled with paint at a constant rate takes 6 min to be filled to 7/10 of its capacity . How much more time will it take to fill the bucket to full capacity ?

A 18/7
B 10/7
C 29/14
D 18/14

Correct Answer: 18/14

7/10 অংশ পূর্ণ হয় 6 মিনিটে 1 বা ( সম্পূর্ণ) পূর্ণ হয় = 6 × 10 /7 = 60/10 মিনিটে Bucket টি পূর্ণ হতে আরও সময় লাগবে = ( 60/7 - 6) মিনিটে = 60 - 42 /7 = 18/7 মিনিটে
