If one-seventh of a number exceeds its eleventh part by 100, then the number is :

If one-seventh of a number exceeds its eleventh part by 100, then the number is : Correct Answer 1925

Let the number be x
Then,
$$\eqalign{ & \Rightarrow \frac{1}{7}x - \frac{1}{{11}}x = 100 \cr & \Rightarrow \frac{{4x}}{{77}} = 100 \cr & \Rightarrow x = \frac{{7700}}{4} \cr & \Rightarrow x = 1925 \cr} $$

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number. Row I: 9,11, 34 Row II: 16, 9, 8 What is the difference between the resultant numbers in the first row and the second row

If the sum of the total time taken by boats X1 to travel D km each upstream and X2 to travel downstream is 4 hours and the sum of the total time taken by boats X1 to travel downstream and X2 to travel upstream the same distance D km each is 12 hours. Time taken by X2 to travel upstream exceeds its downstream time by t1 hours. Similarly, the time taken by X1 to travel upstream exceeds its downstream time by t2 hours. What is the value of (t1 - t2)?
The popular notion that a tree's age can be determined by counting number of internal rings in its trunk is generally true. Howeevr, to help regulate the internal temperature of the tree, the outermost layers of wood of the Brazilian ash often →peel away when the temperature exceeds 95 degrees Fahrenheit, leaving the tree with fewer rings than it would otherwise have. So only if the temperature in the Brazilian ash's environment never exceeds 95 degrees Fahrenheit →elav eing the tree with fewer rings than it would otherwise have. So only if the reliable measure of the tree's age. Which of the following is an assumption on whish the argument above depends?
