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

The difference between a farmer's total agricultural output and the portion of that output consumed on the farm is known as the marketable surplus or net farm income. This surplus represents the quantity of agricultural products that

Correct Answer: $15:12:10$

Solution : Required ratio = $(\frac{1}{4}):(\frac{1}{5}):(\frac{1}{6})$
= $(\frac{1}{4}×60):(\frac{1}{5}×60):(\frac{1}{6}×60)$ [Multiplying each fraction by LCM of (4, 5 and 6) i.e., 60]
= $15:12:10$
Hence, the correct answer is $15:12:10$.

Correct Answer: 1856

Correct Answer: 0.2

Solution : $(0.08 \% \text { of } 0.008 \% \text { of } 8)^{\frac{1}{9}}$
$= (8 × \frac{0.008}{100} × \frac{0.08}{100})^{\frac{1}{9}}$
$= [\frac{8 × 8 × 8}{100 × 1000 × 100 × 100}]^{\frac{1}{9}}$
$= [(\frac{2}{10})^9]^{\frac{1}{9}}$
$=\frac{2}{10}$
$​​​​​​​= 0.2$
​​​​​​​Hence, the correct answer is 0.2.
