Question 78: (February 14th, 2015) Answer



Answer:72.
Based on the conditions given, H and E are two digits and E is twice the value of H.
So the possibilities are 12, 24, 36, 48.
When the number is multiplied by 3, the units place number in the resulting number supposed to be
same as tens place number in the original number.
12, when multiplied by 3 gives 36 and it doesn't satisfy the condition.
Similarly 36 and 48 doesn't satisfy the condition.
Only 24 when multiplied by 3 gives 72 and the condition is satisfied.
So the value of AH is 72.
