Question

one number is 5 times another if 18 is subtracted from the greater the remainder will be 3 times the smaller find the number

Answer 1

let the smaller number be x
let the larger number be y
then according to question
y= 5x............(1)
y-18=3x
5x-18= 3x (from(1) )
5x-3x= 18
2x = 18
x= 9
y= 5x
y= 9*5=45

Answer 2

let the smallest number be x
so, the greatest number will be 5x (it is shown that one number is 5 times greater than other)
18 is subtracted from greater number I.e. 5x-18
and it is equal to 3 times smaller number I.e.
5x-18=3x
5x-3x=18
2x=18
x=18/2
x=9
x is smaller number
so smaller number is 9
noe to get bigger number multiply 5times 9 I.e. 5×9=45
small number is 9
big number is 45


hope it helps
