Options

A. 16,8
B. 25,5
C. 36,4
D. 49,7

Answer

A

Explanation

The pattern is as follows
First row = `"(second row)"^2 i.e., 1^2 = 1, 2^2 = 4, 3^2 = 9, 4^2 = 16 `
and third row = 2 x (second row) i.e.,
` 2xx 1=2, 2 xx 2 = 4, 3 xx 2=6, 4 xx 2 = 8`
Therefore, Missing numbers in first and third row are `4^2 ` i.e 16 and 4 x 2 i.e. 8 respectively
