Question

54+43=2 60+51=10 62+72=?

Answer 1

54 + 43 = 2

60 + 51 = 10

62 + 72 =

You need to find a pattern in the whole question

For 54 + 43,

5 – 4 = 1 ad 4 – 3 = 1. If we add the answer it will be 2

Similarly, in 60 + 51,

6 – 0 = 6, 5 – 1 = 4. On adding them we get, 6 + 4 = 10

For 62 + 72  

6 – 2 = 4, 7 – 2 = 5. On adding them the answer will be 2 + 5 = 9
