Correct Answer: Only I

Solution : Statement I:
The expenditure of R in year Y1 and Y2 together = 600 + 500 = 1100
The expenditure of S in year Y3 and Y4 together = 700 + 500 = 1200
Percentage of the expenditure of R in years Y1 and Y2 together to the expenditure of S in years Y3 and Y4 together = $\frac {1100}{1200}$ × 100 = 91.66%
Statement I is not correct.
Statement II:
Total expenditure of company S = 1200 + 900 + 700 + 500 + 400 = 3700
Total expenditure of company R = 600 + 500 + 800 + 400 + 1000 = 3300
Percentage of the total expenditure of company S to the total expenditure of company R = $\frac{3700}{3300}$ × 100 = 112.12%
Statement II is correct.
Hence, the correct answer is only I

Correct Answer: 296

Solution : The correct option is 296.

There were 296 members in the Provisional Parliament of India, commonly known as the Constituent Assembly of India. These people were in charge of writing India's Constitution, which was enacted on January 26, 1950, when India became a republic. This assembly, comprised of members from various princely kingdoms, provinces and other groupings, was critical in creating India's post-independence political and constitutional framework.

Correct Answer: 22%

Solution : Given. Time = 18 years
Let the principal be $x$.
The sum of money after 18 years = $5x$
Simple interest = $5x-x=4x$
Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
$⇒4x=\frac{x× \text{Rate}×18}{100}$
$\therefore$ Rate = $\frac{400}{18}=22.22\approx 22$%
Hence, the correct answer is 22%.

Correct Answer: $1$

Solution : Given: Let the values of $\cos20°=m$ and $\cos70°=n$
If $A+B=90°$, then $\cos^2 A+\cos^2 B=1$
Here, $70°+20°=90°$
$m^2+n^2= \cos^2\ 20°+\cos^2\ 70°$
$⇒m^2+n^2= 1$
Hence, the correct answer is $1$.

Correct Answer: 1400

Solution : The perfect squares between 120 and 300 are 121, 144, 169, 196, 225, 256, and 289.
Thus, the sum of the numbers is 121 + 144 + 169 + 196 + 225 + 256 + 289 = 1400
Hence, the correct answer is 1400.

Correct Answer: Mid-latitude grasslands

Solution : The correct answer is Mid-latitude grasslands.

The biome known as the world's "Bread Basket" is often connected with Mid-Latitude Grasslands or Temperate Grasslands. These grasslands are noted for their high agricultural productivity, and are home to a substantial portion of the world's grain, and cereal crops, making them critical to global food production. The Great Plains of North America, the Pampas of South America, the Eurasian steppes, and sections of Australia are all examples.
