Question

13)In a two digit number the sum of the digits is 7. If the number with the order of the number.
digits reversed is 28 greater than twice the unit's digit of the original number, find the number.
14 )A number of two digits exceeds four times the sum of its digits by 6 and it is increased
by 9 on reversing the digits. Find the number.
the quotient is 8. ​

Answer 1

Answer:

43

Step-by-step explanation:

Let the two digit number be xy;  

We can written it as 10x+y ; Number reverse is 10y+x       (yx)

x+y=7;                                    (Equation 1)

10y+x=28+2(y)                      (Equation 2) Given

8y+x=28

From y=3,   x=4

So, the number is = 10x+y=

                             = 10(4)+3

                             = 43
