If the sum of two consecutive numbers is 91 and one number is x, then the other number is _____
EVALUATION
Here it is given that the sum of two consecutive numbers is 91
One number is x
Then other number = 91 - x
We now solve it as below
One number is x
Other number is x + 1 or x - 1
We take Other number as x + 1
Now x + x + 1 = 91
⇒ 2x + 1 = 91
⇒ 2x = 90
⇒ x = 45
Hence the two consecutive numbers are 45 and 46
