Question

Problem 1.17 Three numbers A, B and C are such that the difference between the highest and the second highest two-digit numbers formed by using two of A, B and C is 5. Also, the smallest two two-digit numbers differ by 2. If B> A > C, then what is the value of B? (a) 1 (b) 6 (c) 7 (d) 8​

Answer 1

Answer:

B-A=5

A-C=2

Here there are three unknowns A,B and C, and to solve them we need three equations. But only two equations as shown above are given.
