Q 13) PI*(10)^2*(35/60)=183.3 sq.cm

.99999999.......=1 - ( 1 / ( 10 * infinity ) ) =1 - ( 1 / infinity ) =1 - 0 =1

(1*2)+0=2 (2*2)-0=4 (4*2)+1=9 (9*2)-1=17 (17*2)+4=38 (38*2)-4=72 (72*2)+17=161 (161*2)-17=305 (305*2)+72=682 (682*2)-72=1292 1 , 2 , 4 , 9 , 17 , 38 , 72 , 161 , 305 , 682 ,...

if i was right this competition isn't fair as the guy with the black dot will never be able to know his color

sorry i posted a wrong answer then delete it

(1*2)+0=2 (2*2)-0=4 (4*2)+1=9 (9*2)-1=17 (17*2)+4=38 (38*2)-4=72 (72*2)+9=153 (153*2)-9=297 1 ,2 ,4 ,9 ,17 ,38 ,72 ,153 ,297

RajdeepCEHere is another mathematics teaser : Use only 1, 3, 4, & 6 to derive the number 24. You have to follow some rules, ->> use only standard arithmetic expression...
