Question

when a number is divided by 9 the remainder is 8 and when divided by 10 the remainder is 9 find twice of the number​

Answer 1

Let the number be x

x divided by 10 gives remainder 9

x divided by 9 gives remainder 8

19 divided by 10 gives remainder 9

but 19 divide by 9 does not give remainder 8

Similarly

29 , 39, 49, 59, 69 and 79

when divided by 10 gives remainder 9

but when divided by 9 does not give remainder 3

Next,

89 when divided by 10 gives remainder 9

89 when divided by 10 gives remainder 9and

89 when divided by 10 gives remainder 9and 89 when divided by 9 gives remainder 8 !!

Therefore the number is 89

and twice the no. is 89×2=178

Answer : 178
