Question

if B+C =12, then find the values of A, B and C if AB+7C is equal to 102​

Answer 1

Answer:

From the given number, B+C is either 2 or the two digit number that gives the unit digit as 2. It is given that B ≠ 0, C ≠ 0, If B or C = 5 or 7, then A should be 3, then it becomes A+B+C = 14 Or else, if B= C = 6, and A = 2, we will get A+B+C=14
