Question

In a 2 digit no unit's place is halved and tens place is doubled. The differencce between the nos is 37.Digit in unit's place is 2 more than tens place.

Answer 1

Answer:

Step-by-step explanation:

let the digit at tens place is x and units place is y

originol number is 10x+y

given that , y=x+2

y-x=2 [1]

10*x*2+y/2-(10x+y)=37

by solving this , we get

20x-10x-y/2=37

10x-y/2=37

by solving this we get

20x-y=74 [2]

by adding both we get 19x=76

so x=4

by putting the value of x in 1 we get

y=6

so the number is 10*4+6=46

answer is 46
