The answer is B.Because,(upper left corner X upper right corner) - (lower left corner X lower right corner) = Middle Number.
Ans 18: (Master Answer)
Class : Class 1
The correct answer is B.
In the first figure 25 X 15 - 12 X 14 = 207
In the 2nd figure, 16 X 17 - 10 X 12 = 152
Similarly, in the third figure, 25 X 25 - 21 X 18 = 247
Hence, the missing number is 25

E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
Ans 3:
Class : Class 7
in simple terms "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.
