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.)

Correct Answer: 13 – 163


Solution : Let's check each option –
First option: (13 – 163); 13 2 – 4 = 169 – 4 = 165 ≠ 163
Second option: (9 – 77); 9 2 – 4 = 81 – 4 = 77
Third option: (18 – 320); 18 2 – 4 = 324 – 4 = 320
Fourth option: (24 – 572); 24 2 – 4 = 576 – 4 = 572

So, only the first option is different from the others. Hence, the first option is correct.
