step 1- SINCE H+M=H, M SUD BE 9, NOW WE HV TO MAKE H+M=H, TAKE H=3(ASSUME)
HERE 9+3+1(CARRY)= 13( 3 WITH 1 CARRY)
STEP 2: SINCE B+CARRY=H, B SUD BE 2.
REMEMBER..ALL Hs ARE NOW 3.
STEP 3:
P*D=HM, H IS 3..
IF WE TAKE P=8, IT GIVES P*H=D (8*3=24)[4 AS UNIT DIGIT IN FIRST ROW]
FROM HERE IF WE TAKE D=4,THEN IT ALSO GIVES P*D=32(P*D=HM AND WE KNOW THAT H=3)
STEP4:
STEP 4:
A*H=P MEANS A SUD BE 6(A*3=carry+8)
SINCE A=6, A*M=Z(WE KNOW M=9 ) SO 6*9=54(CARRY+4)=> Z=5
SINCE M+Z+P=B( CARRRY+ 2) MEAN 9+Z+8= CARRY +2 ,Z SHOULD BE 5
AND D+S=Z MEAN 4+S=5 GIVES S=1.
NOW LOOK...S=1, Z=5 M=9 SO N MUST BE 7
SO HERE A=6 B=2 D=4 H=3 M=9 N=7 P=8 S=1 Z=5 - 10 years agoHelpfull: Yes(4) No(0)
