### Question 1

The ratio of surface area to the volume of a cuboids is 9 : 1, and the sum of reciprocals of two edges is 62, what is the reciprocal of the third edge?

### Question 2

How much water flows per hour through a pipe of radius 42 cm, if water flows at 10 km/h? Take π = 22/7.

**A**

5544 cu. m.

**B**

5546 cu. m.

**C**

5542 cu. m.

**D**

5548 cu. m.

**Soln.**

**Ans: a**

In one hour, a water column of length 10 km is delivered through the cylindrical pipe. The equivalent volume is ${22 × 42 × 42 × 10 × 1000}/{7 × 100 × 100}$, which can easily be cancelled to get 5544 cu. m.
