Answer 1

Answer:

follow.me

let the number be abcd.

According to the statement:

a+c=4

b+d=15

d−a=7

From the equations, following conclusions can be drawn:

a can be 1,2,3,4 from a+c=4, but a cannot be 3 and 4 from d−a=7 as d exceeds 9, which is not possible.

For a=1, the number is 1738 and for a=2 the number is 2629

Hence, the required number is 1738 as we were supposed to find the least value.
