It’s time to play “what’s my number? ” the number will now tell you about “i am a 4-digit even number where the sum of my digits is half of the jersey number made famous by baseball player jackie robinson. if you take my second digit and multiply it to my last digit, the result is a two- digit number – the tens digit in this result is my third digit. my last digit is one more than my third digit and one less than my first digit. if you multiply my third digit to itself, you will get my second digit.” what’s my number?

let the number be abcd

then a + b + c + d = 21

also  we are given:-

d = c + 1

d = a - 1

c^2 = b

a - 1 = c + 1     (as they are both = d)

So c = a - 2

and b = (a - 2)^2

So substitute for b , c and d in the first equation we get

a + (a - 2)^2 + a - 2 + a - 1 = 21

a + a^2 - 4a + 4 + a - 2 + a - 1 = 21

a^2 - a - 20 = 0

(a - 5)(a + 4) = 0

So a = 5    (ignore the negative -4)

Now using the above results   d = 5 - 1 = 4

c = 5 - 2 = 3  and b = c^2 = 9

So your number is 5934  (answer)

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
