Question 1
4 / -1

A can do a piece of work in $12$ hours, while B can do it in $8$ hours. If A and B both work together, so in how many hours the work will be completed?

A
$10$ hours

B
$4$ hours

C
$5$ hours $15$ minutes

D
$4$ hours $48$ minutes

Solution

Given:

A can complete the work in $12$ hours

A’s one - hour work $= \frac{1}{12}$

B can complete the work in $8$ hours

B’s one - hour work $= \frac{1}{8}$

Let the total time taken by A and B to complete the work be $x$ hours

A and B‘s one - hour work $= \frac{1}{12} + \frac{1}{8}$

$\frac{1}{12} + \frac{1}{8} = \frac{1}{x}$

⇒ $x = 4.8$ hr $= 4$ hr and $(0.8 \times 60)$ min $= 4$ hours $48$ minutes

The total time is taken by A and B to complete the work is $4$ hours and $48$ minutes
Question 2
4 / -1

$A$ can do a piece of work in $14$ days and $B$ can do it in $21$ days. They begin together but $3$ days before the completion of the work, $A$ leaves the work. The total number of days to complete the work is?

A
$10 \frac{1}{4}$

B
$10 \frac{1}{5}$

C
$7 \frac{1}{5}$

D
$7 \frac{4}{5}$

Solution
Question 3

A bicycle wheel makes $5000$ revolutions in moving $11 \mathrm{~km}$. What is the radius of the wheel? (Assume $\pi=\frac{22}{7}$)

A
$17.5 \mathrm{~cm}$

B
$35 \mathrm{~cm}$

C
$70 \mathrm{~cm}$

D
$140 \mathrm{~cm}$

Solution
Question 4
4 / -1

A cube has sides that are $4 \mathrm{~cm}$ each, and the dimensions of a cuboid are $2 \mathrm{~cm} \times 3 \mathrm{~cm} \times 4 \mathrm{~cm}$. Find the positive difference between the volume of the cube and that of the cuboid.

A
$120 \mathrm{~cm}^3$

B
$40 \mathrm{~cm}^3$

C
$20 \mathrm{~cm}^3$

D
$60 \mathrm{~cm}^3$

Solution

Volume of cube $= 4^3 =64$

Volume of cuboid $=2×3×4=24$

Positive difference between the volume of the cube and that of the cuboid$=64-24=40~cm^3$
Question 5

Which of the following pattern of dice can be formed when the sheet given below is folded?

A
Both A & C

B
