Select the set in which the numbers are related in the same way as are the numbers of the following set.
(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)
(182, 170, 97)
(156, 128, 92)
Answer & explanation
Correct answer: option 4
The pattern followed is:
1st no. - Half of 2nd no. = 3rd no.
Here,
182, 170, 97 ⇒ 182 - \(\frac{170}{2}\) = 182 - 85 = 97
156, 128, 92 ⇒ 156 - \(\frac{128}{2}\) = 156 - 64 = 92
Similarly,
After checking all options, we get the answer from option (4)
138, 130, 73 ⇒ 138 - \(\frac{130}{2}\) = 138 - 65 = 73
