Question

The difference between a 2 digit number and the number obtained when unit's place is halved and ten's place is doubled is 37. digit in unit's place is 2 more than ten's place .find the number?

Answer 1

lets first write down the numbers which follow "digit in unit's place is 2 more than ten's place"

13

24

35

46

57

68

79

it cant be any number which ends with an odd number, the difference wouldnt be 37 then. it narrows down to

24

46

68

the number should also be the multiple of an odd number, other wise the difference wouldnt be odd, it would be even

this leaves us with the only answer

46, you can then confirm it

4*2 = 8 , 6/2 = 3

83-46 = 37
