Question

Tony asked his friend to guess his mathematics test score. He gave these hints to help his friend guess:

-It has two digits

-The digit in the tens place is two more than twice the digit in the ones place.

-The number formed by reversing the order of the digits is 5 more than 3 times the sum of the digits.

What was his test score?

Answer is 83, but i'm not sure how it is worked out.

Answer 1

just write the words as math. If the tens digit is t and the units digit is u, then:

t = 2u+2
10u+t = 5+3(t+u)

solve for t and u

Answer 2

-It has two digits

_ _

-The digit in the tens place is two more than twice the digit in the ones place.

41 or 62 or 83

-The number formed by reversing the order of the digits is 5 more than 3 times the sum of the digits.
