Correct Answer: torque

Solution : The correct answer is torque.

The measure of the force that can cause an object to rotate about an axis is called torque. Torque is the product of force and the distance from the axis of rotation to the point where the force is

Correct Answer: 42.1

Solution : Total amount spent by S = 16
Total amount spent by T and R = 20 + 18 = 38
$\therefore$ Percentage of S = $\frac{\text{S}}{\text{T + R}}$×100
= $\frac{16}{38}×100$
= 42.1%
Hence, the correct answer is 42.1.

Correct Answer: 1.59

Solution : Average number of children per family
$=\frac{\sum{\text{Number of children}\times\text{Number of families}}}{\sum{\text{Total number of families}}}$
$=\frac{0\times4+1\times22+2\times15+3\times6+4\times2}{4+22+15+6+2}$
$=\frac{22+30+18+8}{49}$
$=\frac{78}{49}$
$=1.59$
Hence, the correct answer is 1.59.

Correct Answer: (7, 169) 

Solution : Let's check the given options –
First option: (25, 49); 25 = 5² and 49 = 7²

Second option: (121, 169); 121 = 11² and 169 = 13²
Third option: (7, 169); 169 = 7 is not a perfect square

Correct Answer: 120

Solution : Side of the rhombus = 13 cm
One of the diagonals = 24 cm
$side^2 = (\frac{d_1}{2})^2+(\frac{d_2}{2})^2$
⇒ $13^2=(\frac{24}{2})^2+(\frac{d_2}{2})^2$
⇒ $169=144+(\frac{d_2}{2})^2$
⇒ $(\frac{d_2}{2})^2=25$
⇒ $\frac{d_2}{2}=5$
⇒ $d_2=10$
Area of a rhombus = $\frac{d_1 × d_2}{2}$
= $\frac{24\times10}{2}$
= $120\ cm^2$
Hence, the correct answer Is

Correct Answer: marketable surplus

Solution : The correct option is a marketable surplus
