Question

If 1 2 5 3 = 13 , 1 9 5 4 =17 then 1 4 5 6=? Plz explain the answer from options a. 21 b.25 c.27 d.29

Answer 1

• Given:-1 2 5 3 = 13 , 1 9 5 4 =17

• To find:- 1 4 5 6=?

• Solution:- According to the series,the format is like

A B C D = (C×D)-(A×B)+ X,Y,Z= Result

and X=0,Y=3,Z=6

(0) 1 2 (3) 4 5 (6)

so,1 2 5 3 = (5×3)-(1×2)+0= 13 [X=0]

1 9 5 4 = (5×4)-(9×1)= 11+6= 17 [Z=6]

now we have to use Y=3

so,1 4 5 6= (5×6)-(1×4)= 30-4+3=29 [Y=3]

So the series is 1 2 5 3 = 13 , 1 9 5 4 =17 then 1 4 5 6=29

The final answer is d. 29
