Question

The digit in 10 place of two digit number is 3 more than the digit in unit place if unit digit in to what is the number A. 52 b. 25 c. 50 d. 23

Answer 1

Let the digit at unit's place be x.digit at Ten’s place = x+3Number formed :10 × (x+3) + x = 10x +30= x = 11x+30if x=2
then the number will be- 11*2+30= 22+30= 52
if x=5
then the number will be- 11*5+30=55+30= 85
if x=0
then the number will be- 11*0+30=0+30= 30
if x=3
then the number will be- 11*3+30=33+30= 63

Hence, only one condition fulfill the given options.So, unit's place be x= 2 & Ten’s place digit = x+3= 5
Hence, the number is 52.
