Question 6
The sum of two numbers is 135 and their HCF is 9. How many such pairs of numbers can be formed ?
Solution
Let the two numbers be $$9x$$ and $$9y$$, where $$x$$ and $$y$$ are co prime numbers.
=> $$9x+9y=135$$
=> $$x+y=\frac{135}{9}=15$$
Now, pairs of natural numbers having sum 15 and co prime are = (1,14), (2,13), (4,11), (7,8)
Thus, 4 such pairs can be formed.
=> Ans - (C)
