Two quantities A and B are given in the following questions. You have to find the value to both A and B by using your knowledge of mathematics and choose the most suitable relation between the magnitude of A and B from the given options.
Quantity A - Two digit number. When the digits of this number are reversed, it increases by 18.
Quantity B - Profit percent. A discount of 5% is given while the marked price is Rs. 5400. Cost price is Rs. 4000.
Quantity A ≥ Quantity B
Quantity A ≤ Quantity B
Quantity A = Quantity B or no relationship can be established
Quantity A > Quantity B
Quantity A < Quantity B
Correct answer
Quantity A ≥ Quantity B
In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for both quantities and choose the correct option.
Quantity A: If the average of five consecutive numbers is 32, find the fifth number.
Quantity B: Find the average of 7 consecutive even numbers starting from 26?
Quantity A > Quantity B
Quantity A < Quantity B
Quantity A ≥ Quantity B
Quantity A ≤ Quantity B
Quantity A = Quantity B
Correct answer
Quantity A > Quantity B
