Select the missing number from the given responses.
`{:(92,70,48),(64,53,42),(52,45,?):}`

Options

A. 36
B. 40
C. 38
D. 42

Answer

C

Explanation

First Column
`92+64+52=208`
Second Column
`70+53+45=168`
The difference between the sums of the three numbers of the first column and second column is 40.
Third Column
therefore, the sum of the three numbers of the third column
would be `168-40=128`
Thus,
`?=128-(48+42)`
`rArr128-90=38`
