The L.C.M of 22, 54, 108, 135 and 198 is

A) 330	B) 1980
C) 5940	D) 11880

Answer & Explanation Answer: C) 5940

Explanation:

22 = 2 x 11

54 = $2 \times 3^{3}$

108 = $2^{2} \times 3^{3}$

135 = $3^{3} \times 5$

198 = $2 \times 3^{2} \times 11$

$∴ L . C . M = 2^{2} \times 3^{3} \times 5 \times 11 = 5940$

Q:

A booster pump can be used for filling as well as for emptying a tank. The capacity of the tank is 2400 $m^{3}$ . The emptying capacity of the tank is 10 $m^{3}$ per minute higher than its filling capacity and the pump needs 8 minutes lesser to empty the tank than it needs to fill it. What is the filling capacity of the pump?

A) 50 m^3/min	B) 60 m^3/min
C) 72 m^3/min	D) None of these

Answer & Explanation Answer: A) 50 m^3/min

Explanation:

Let the filling capacity of the pump be x $m^{3}$ /min.

Then, emptying capacity of the pump=(x+10) $m^{3}$ /min.

so, $\frac{2400}{x} - \frac{2400}{x + 10} = 8 \Leftrightarrow x^{2} + 10 x - 3000 = 0$

$\Rightarrow (x - 50) + (x + 60) = 0 \Leftrightarrow x = 50$
