From the example, the formula is:
(the multiplication of the three lower numbers) ÷ 10= the upper number

From example 1:
(3×8×5)÷10=x
120÷10=x
12=x
Therefore x=12

From example 2:
(7×2×15)÷10=x
210÷10=x
21=x
Therefore x=21

Now go ahead and solve!!!

My 2cents though...smiley

by the time you used this formula to solve the remaining questions, the answers are inaccurate. But it solves the first two questions
(5×6×5(²))=150÷10= 15
(? ×8×5(5²))= 40÷10 =4
(4×8×5)=160÷10=

Is that how he solved it? You are the one rather using a wrong approach from number 2. How would multiply all the values when it should be like this

(8*10) ÷ (8*5) = 80÷40= 2

If I am an empty vessel in reasoning and mathematics , then you don't even exist when it comes to reason or mathematics.
For your information no quantitative reasoning meet for primary school I can't figure out.
