The selling price of plot is directly proportional to the square of area of plot in m2. If the cost price of square shaped plot is Rs. 50000 and the profit percent of a dealer is 25% on selling square shaped plot then find the cost price of rectangular shaped plot if the dealer gains 50% on selling of rectangular plot where the length and breadth of rectangular plot is 30 m and 20 m while the side length of square plot is 20 m.
A rectangular plot has a concrete path running in the middle of the plot parallel to the breadth of the plot. The rest of the plot is used as a lawn which has an area of 420 sq. m. If the width of the path is 4 m and the length of the plot is greater than its breadth by 36 m, what is the area of the rectangular plot? 
The use of energy from sunlight by plants doing photosynthesis is the basis of life on earth. Which of the following statement is correct for photosynthesis? 1. chlorophyll (green pigment of the leaf), light, and CO2 are required for photosynthesis to occur. 2. photosynthesis occurs only in the green parts of the leaves in the presence of light.  3. chlorophyll is the chief pigment associated with photosynthesis.
A big rectangular plot of area 4320 m2 is divided into 3 square-shaped smaller plots by fencing parallel to the smaller side of the plot. However some area of land was still left as a square could not be formed. So, 3 more square-shaped plots were formed by fencing parallel to the longer side of the original plot such that no area of the plot was left surplus. What are the dimensions of the original plot ?
The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
A student has created a plot of y(t)=t2. He is need to show another graph of z(t)=t3 in the same plot. But every time he hits the plot() function- MATLAB generates a plot of z(t) vs t but on a different window. What is the error?
Consider the following statements.
1. Carbon dioxide, chlorophyll and sunlight all are essential for photosynthesis.
2. Rate of photosynthesis is maximum in red light and minimum in green light.
3. Increase in O2 concentration decrease photosynthesis.
Which of the statements given above is/are correct about photosynthesis ?
In a horticulture experiment , 200 seeds were planted in plot I and 300 were planted in plot II. 57 percent of the seeds in plot I germinated and 42 percent of the seeds in plot II germinated, what percent of total numbers of planted seeds was germinated?
