“Study the first 2 circles in each row and complete the 3rd one”

For the third circle, in the first row, the answer is 4

For the third circle, in the second row, the answer is 20

For the third circle, in the third row, the answer is 20

For the circles in the first row:

For the first circle,

5 × 2 = 10 ; 10 ÷ 2 = 5

For the second circle,

3 × 4 = 12; 12 ÷ 2 = 6

∴ For the third circle,

2 × 4 = 8; 8 ÷ 2 = 4

∴The answer is 4

For the circles in the second row:

For the first circle,

4 × 5 = 20; 20 - 8 = 12

For the second circle,

6 × 5 = 30; 30 - 17 = 13

∴ For the third circle,

5 × 5 = 25; 25 - 5 = 20

∴ The answer is 20

For the circles in the third row:

For the first circle,

16 ÷ 4 = 4; 4 + 4 = 8

For the second circle,

24 ÷ 4 = 6; 6 + 6 = 12

∴ For the third circle,

40 ÷ 4 = 10; 10 + 10 = 20

∴ The answer is 20

Hence,

For the third circle, in the first row, the answer is 4

For the third circle, in the second row, the answer is 20

For the third circle, in the third row, the answer is 20
