Find two consecutive odd numbers such that two fifths of the smaller number exceeds two ninths of the larger by 4
Solution :
Let one odd number be ' 2n + 1 '
This is smallest odd number .
Other consecutive odd number be ' 2n + 3 '
This is largest odd number .
A/c , " Two fifths of the smaller number exceeds two ninths of the larger by 4 "
First consecutive smallest odd number :
= 2n + 1
= 2(12) + 1
= 24 + 1
= 25
Second consecutive largest odd number :
= 2n + 3
= 2(12) + 3
= 24 + 3
= 27
Alternative : You may solve this question by taking ' x ' as smallest consecutive odd number and ' x + 2 ' as biggest consecutive odd number .
