Question
Select the set in which the numbers are related in the
same way as are the numbers of the following sets. (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) (4, 13, 5) (3, 12, 6)Solution
first + third+ first= second 4+5+4=13 3+6+3=12 so, 5+7+5=17Â
