Correct Answer: 9 : 81 : 45
Solution : Let's check the options –
First option: 20 : 400 : 200; 20 2 = 400 and 400 ÷ 2 = 200 Second option: 9 : 81 : 45; 9 2 = 81 and 81 ÷ 2 = 40.5 ≠ 45 Third option: 13 : 169 : 84.5; 13 2 = 169 and 169 ÷ 2 = 84.5 Fourth option: 25 : 625 : 312.5; 25 2 = 625 and 625 ÷ 2 = 312.5
So, the second option is different from the other three options as here 81 ÷ 2 = 40.5 ≠ 45 . Hence, the second option is correct.
