Correct Answer: 15
Solution : Given: 10 – 3 = 12, 12 – 4 = 13, 14 – 5 = 14 Add 5 to the difference of the numbers on the L.H.S. to get the R.H.S. Like, 10 – 3 = 12→(10 – 3) + 5 = 7 + 5 = 12 12 – 4 = 13→(12 – 4) + 5 = 8 + 5 = 13 14 – 5 = 14→(14 – 5) + 5 = 9 + 5 = 14 Similarly, for 16 – 6 = ?→(16 – 6) + 5 = 10 + 5 = 15
Hence, the second option is correct.
