E.g. 13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 186.
11 is related to 106 → 11 × 10 - 4 = 106
15 is related to 146 → 15 × 10 - 4 = 146
Similarly, 19 is related → 19 × 10 - 4 = 186
