Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. 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)

Answer 1

The logic followed here is :

So,

150 × 2 = 300

300 = 300 (LHS = RHS)

And,

300 × 2 = 600

600 = 600 (LHS = RHS)

50 × 2 = 200

100 ≠ 200 (LHS ≠ RHS)

And,

200 × 2 = 400

400 = 400 (LHS = RHS)

250 × 2 = 500

500 = 500 (LHS = RHS)

And,

500 × 2 = 1000

1000 = 1000 (LHS = RHS)

50 × 2 = 100

100 = 100 (LHS = RHS)

And,

100 × 2 = 200

200 = 200 (LHS = RHS)

Hence, "Option - (2)" is the correct answer.
