142. In the equation A + B + C + D + E = FG where FG is the two digit number whose value is 10F + G and letters A, B , C , D , E, F and G each represent different digits. If FG is as small as possible. What is the value of G?

**Answer:**** Option B **

**Explanation:**

FG is as large as possible and all the 7 numbers should be different.

By trial and Error method,

9 + 8 + 7 + 6 + 5 = 35....5 is getting repeated twice.

9 + 8 + 7 + 6 + 4 = 34...4 is getting repeated

9 + 8 + 7 + 5 + 4 = 33...3 repeats

9 + 8 + 6 + 5 + 4 = 32

None of the numbers repeat in the above case and 32 is the maximum number FG can have. The value of G is 2.
