Correct Answer: 6 minutes

Solution : Five bells ring together at intervals of 3, 5, 8, 9, and 10 seconds
Calculation: 
By taking the Least Common Multiple for 3, 5, 8, 9, and 10 seconds = 360 seconds 
= 6 minutes 
$\therefore$ All the bell rings together in 6 minutes.

Correct Answer: $2\pi -4$

Solution :
The length of each side of the formed square is $2\;\mathrm{cm}$.
The length of the radii of the circles = $2\;\mathrm{cm}$
The area of square $=(2\;\mathrm{cm})^2 = 4\;\mathrm{cm^2}$
The area of each circle $=\pi \times 2^2 = 4\pi\;\mathrm{cm^2}$
The area of each sector of

Correct Answer: 20

Solution : Let Aman be 100% efficient.
Then Raman will be 125% efficient.
Now, 100% efficient can do work in 25 days,
1% efficient will do work in $25 \times 100$ days.
$\therefore$ 125% efficient can do work in $\frac{25 \times 100}{125}$ = 20 days
Hence, the
