The contractile proteins in a muscle refer primarily to two types of proteins: actin and myosin. Actin is a globular protein that forms thin filaments in muscle fibers. These filaments are involved in muscle contraction

Correct Answer: 702

Solution : Cost of first variety = INR 504
The cost of the second variety = INR 540
The ratio in which rice varieties are mixed = 1 : 1 : 2
Let INR $x$ be the cost of the third variety.
Cost of mixed variety =

Correct Answer: 28 cm

Solution : Volume of cylinder = $\pi r^2h$
The volume of the cylinder can be written as $32y$ and $9y$
The height of the cylinder can be written as $8h$ and $9h$
Since we know that the volume of the cylinder = Area of the base

Correct Answer: 8,242

Solution : Simple interest (SI)= $\frac{\text{Principal × Rate × Time}}{100}$
 SI = INR 11,220
Rate = $16\frac{1}{2}$ = $\frac{33}{2}$%
Time = 8 years 3 months = $8\frac{3}{12}$ = $8\frac{1}{4}$ = $\frac{33}{4}$
According to the question,
11220 = $\frac{\text{P×33×33}}{100×2×4}$
⇒ P = $\frac{11220×800}{1089}$
= $\frac{8976000}{1089}$
= 8242.424
=

Correct Answer: 21

Solution : Given:
If $\sqrt{AFI}\ :\ 13\ ::\ \sqrt{DDA}\ :\ ?$

The position values of A, F, and I are 1, 6, and 9 respectively.
On combining the place values, we get 169.
Now, $\sqrt{169}\ =\ 13$
Thus, $\sqrt{AFI}$ is coded as 13.
Similarly, follow the same

Correct Answer: $\sqrt{63}$

Solution : Given, the distance between the centres of two circles is 12 cm ($d$) and the radii are 5 cm ($r_1$) and 4 cm ($r_2$).
Length of the transverse common tangent line to the circle
= $\sqrt{d^2-(r_1+r_2)^2}$
= $\sqrt{12^2-(5+4)^2}$
= $\sqrt{144-81}$
​​​​​​= $\sqrt{63}\ \text{cm}$
Hence, the

Correct Answer: 1 : 5

Solution : 16 years ago, let my age and my grandfather's age be $x$ years and $9x$ years respectively.
According to the question,
$9x+16+8=3(x+16+8)$
⇒ $9x+24=3x+48+24$
⇒ $6x=48$
⇒ $x=8$
Required ratio 8 years ago,
= $(x+8):(9x+8)$
= (8 + 8) : (9 × 8
