Seriously, I have been on these for almost 5 hours and I have given them to some people to rack their brains in it... Anyone with useful tips?

OP, just like you too, I've only been able to solve the last one. Well, it was the first I attempted sha.
I'd modify as soon as I figure out the rest

Modified: Just figured out another

Am on it.

But Goin with ur method... It won't solve number 13...because the differences in both the row and column is 5. And the final answer Wil be 25, which is not in the option



Sorry...I was wrong... The answer is 15. Kudos bro

Who is confused as well o.... My brain is hot. I am even thinking on how to think.

first one:
Sample 1: 2(1) + √4 = 12 ÷ 3
Sample 2: 2(3) + √4 = 40 ÷ 5
Sample 1: 2(4) + √144 = 320 ÷ 16

So answers are;
21. E
22. E
23. B
24. D
25. D

For the second question:
Samples:

Sample 1: (4×3×2)÷8 = 3
Sample 2: (2×5×30)÷10 = 30
Sample 3: (2×½×4)÷4 = 2

Answers:
16. C
17. B

For the first part using example 1

1 + 3 = 4
4 × 3 = 12

3 - 1 = 2
2 × 2 = 4


21. 7




22. 50



23. 5






24. 25




25. 126

For the second part, using example 2

2 x 5 x 30 = 300
300 ÷ 30 = 10



16. 4


17. 3

The third part, using example 3

3.5 - 2.5 = 1
6.2 - 1 = 5.2

6.2 - 3.5 = 2.7
3.5 - 2.5 = 1
1 × 2.7 = 2.7


11. 7

12. 21

13. 15

14. 10

15. 21

Simple
3-1= 2, 2 sq= 4.
3+1=4, 4×3=12.

5-3=2, 2 sq= 4
5+3=8, 8x5=40

16-4= 12, 12 sq= 144
16+4=20, 20x16= 320

2nd one.

4x3x2=24, 24/8=3
2x5x30=300, 300/10=30
2x 1/2 × 4= 4, 4/2= 2.

3rd one
10-6=4, 40-10=30, 30×4=120 in triangle

12-8=4, 60-12=48, 48×4=192 in triangle.

3.5-2.5= 1, 6.2-3.5= 2.7, 2.7×1= 2.7 in triangle

I only solved the examples.

Seriously, the author Sud have a way of explaining the method jor..

That was their intention when they introduced 3 examples.
If you mean, telling you descriptively, how it was solved, that's like telling you the answer na, abi?
