Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers.
Quantity A: Sum of cubes of single-digit odd numbers
Quantity B: Square of LCM of 7 and 5
First we will find Quantity A,
Quantity A:
Single-digit odd numbers are: 1, 3, 5, 7, 9
Required sum = 13 + 33 + 53 + 73 + 93
= 1 + 27 + 125 + 343 + 729
= 1225
Quantity A = 1225
Quantity B:
LCM of 7 and 5 is 35
352 = 1225
Quantity B = 1225
Clearly, Quantity B = Quantity A
