Solution

The correct option is B 58 45 56
The numbers in the first term of the LHS 10,25 and 26 form a diagonal line
The numbers in the second term of LHS 10,23 and 30 form another diagonal line the first number in these terms is common.The location of these two diagonals in the number triangle is an shown below
similarly the numbers in the first term of RHS 28,47 and 52 forms a diagonal and this diagonal is parallel to the diagonal formed by the numbers 10,25 and 26
Hence the numbers in the second term of RHS should start with 28 and must be in a line parallel to the diagonal formed by the numbers 10,23 and 30. so the numbers in the second term on RHS should be 28,45 and 56
