 Hi and welcome to the session. Let us discuss the following question, question size. Find the values of the letters in the following and give the reasons for the steps involved. Let us now start with the solution. First of all, let us rewrite the given puzzle that is AB plus 37 gives 68. Now clearly you can see some is 60 or above 60 since 10th place of the sum is 6. Now numbers from 23 to 32 when added to 37 we get the sum as 60 or above 60. Now if AB is any number between 23 to 29 then value of A will be 2. Now if A is equal to 2 then one digit of B plus 7 is A equal to 2. Now one digit of B plus 7 is equal to 2 only if value of B is 5. Now when A is 2 and B is 5 then we get 25 plus 37 as 62. So we get value of A is 2 and value of B is 5. So here we have solved the given puzzle. This is our required answer. This completes the session. Hope you understood the solution. Take care and bye for now.
