Question

if the units and tens digit of a five digit number are interchanged .the new number is greater than the old number by 63.the difference between the units and ten digit is
​

Answer 1

Answer:

Let the answer be n = xy =( 10x+y )where X and y are individual digits

Given in question x-y=5 —————equation 1

&

Let's the interchanged digits make the number be m= yx=(10y+x)

So the ratio be like m:n :: 3:8 ( given ).

i.e yx:xy::3:8 = 10y+x : 10x+y :: 3:8

80y+8x=30x+3y

77y-22x=0

7y-2x=0 —————— equation 2

From equation 1 &2

X=7

Y=2

So the number is 72
