Find the missing character in each of the following.

Options

A. 14
B. 11
C. 12
D. 13

Answer

Explanation

`:. sqrt16+sqrt36=10`
`implies 4 + 6 = 10`
`implies 10 = 10`
Also, `sqrt(25)+sqrt(64) = 13`
`implies 5 + 8 = 13`
`implies 13 = 13`
`:. sqrt9 + sqrt81 = ?`
`implies 3 + 9 = ?`
`implies ? = 12`
