1)  

 Simplify   :   33 + 212 + 1224

Answer: 53


SOLUTION 1 :

=     33 + 212 + 1224  

LCM of 3 12 .24 is  24

=  [(3x8) +(2x2) + (12x1)] / 24

= (24+4+12)24

 = (40)24

 = 53

 



2)  

 Simplify   :   13 + 812 + 1524

Answer: 138


SOLUTION 1 :

=     13 + 812 + 1524  

LCM of 3 12 .24 is  24

=  [(1x8) +(8x2) + (15x1)] / 24

= (8+16+15)24

 = (39)24

 = 138
