is 3 more than the digit in the tens place. What is the number?
1) 63
2)36
3) 24
4) 40​

Answer 1

Answer:2)36

Step-by-step explanation:

Let the no. at ten's place be x.

Therefore,the no. at units place is x+3.

The no. = 10x+x+3 = 11x+3

Sum of the digits = x+x+3 = 2x+3

Acc to the question

(11x+3)/(2x+3)=4

By cross multiplication

11x+3 = 8x+12

3x = 9

x = 3

The number = 11x+3 = 11×3+3 = 33+3 = 36
