A tank is 1/3 parts full with water. If 8 liters of water is added, the tank becomes 5/6 parts full. What is the capacity of the tank?

A 16

B 24

C 48

D None

Solution

Correct Answer: Option A

ধরি,
ট্যাংকের ধারণক্ষমতা = x লিটার

প্রশ্নমতে,
(x/3) + 8 = 5x/6
⇒ (5x/6) - (x/3) = 8
⇒ (5x - 2x)/6 = 8
⇒ 3x = 48
⇒ x = 48/3
⇒ x = 16

অর্থাৎ ট্যাংকের ধারণক্ষমতা = 16 লিটার
