Subject: General Aptitude · Chapter: Volume and Surface Area · Exam: · Marks: · Difficulty:

If a river 2.5 m deep and 45 m wide is flowing at the rate of 3.6 km per hour, then the amount of water that runs into the sea per minute is

(a)6650 cu. m

(b)6750 cu. m

(c)6850 cu. m

(d)6950 cu. m

Answer

Answer (as printed): B

Explanation

Length of water column flown in 1 min $$=\left(\frac{3.6 \times 1000}{60}\right) \mathrm{m}=60 \mathrm{m} .$$ ∴ Volume flown per minute $=(60 \times 45 \times 2.5) \mathrm{m}^{3}=6750 \mathrm{m}^{3}$.
