if 532=1561028, 641=244630, 785=564035123 then 821=?

Check your answer:-

Click here to See Solutionhere the logic is

R1 = first digit * second digit

R2 = second digit * third digit

R3 = third digit * first digit

so final number is

R1R2R3(R1+R2+R3 – second digit)

for 532=1561028

R1 => 5*3 = 15

R2 = 3*2 = 6

R3 = 2*5 = 10

final number = 15610(15+6+10-3) => 1561028

same logic is true for new two numbers as well

by the same logic for 821

R1 = 8*2 = 16

R2 = 2*1 = 2

R3 = 1*8 = 8

final number 1628(16+2+8-2) => 162824
