Select the set in which the numbers are related in the same way as are the numbers of the following sets:
(99, 199, 1199)
(15, 115, 1115)
(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 & explanation
Correct answer: option 2
(99, 199, 1199)
(15, 115, 1115)
The logic followed here is :
Ist number + 100 = Second number and Second number + 1000 = IIIrd number
As
99 + + 100 = 199 and 199 +1000 = 1199
15 +100 = 115 and 115 +1000 = 1155
Similarly
33 +100 = 133 and 133 + 1000 = 1133
