Correct Answer: Rs. 13800

Solution : Given:
Total simple interest = Rs. 7728
Rate = 7% per annum
Time: 8 years.
Simple interest (SI) = $\frac{(\text{Principal × Rate × Time})}{100}$
Let the principal amount be P.
So, 7728 = $\frac{P × 7 × 8}{100}$
⇒ P = $\frac{772800}{7 × 8}$

Correct Answer: $36 + 12\pi\ \text{cm}$

Solution :
The length of the string not in contact with the circle = $2r+2r+2r=6r=6\times6=36$
By symmetry, the angle swiped by the string on one circle = $120^\circ$
Length of the string touching circle = $\frac{2\pi r}{3}+\frac{2\pi r}{3}+\frac{2\pi r}{3}=\frac{6\pi r}{3} = 2\pi r$
$=2\pi

Correct Answer: misleading

Solution : The correct choice is the fourth option.

In the context provided, the word lying refers to the act of not telling the truth or providing false information. The synonym misleading aligns closely with this meaning. This refers to something that gives the wrong idea

Correct Answer: 6

Solution : $y^{3}-y=y(y^{2}-1)=y(y-1)(y+1)$
This product includes three consecutive integers: $y-1$, $y$, and $y+1$

Correct Answer: 21 cm

Solution : Let the radius of the first circle be $r_1$.
Circumference of the first circle $=2\pi r{_1}$
⇒ $308 = 2×\frac{22}{7}×r{_1}$
⇒ $r_1$ = 49 cm
Let the radius of the 2nd circle be $r_2$.
Circumference of the 2nd circle $=2\pi r{_2}$
⇒ $440 =
