Answer 2

Answer:

1.  cement=23/5 kgs = 4.6 kgs

   sand = 23/5 + 1/2 = 23x2/10

5/10 = 5.1 kgs                                                                                                                                              

cement+sand = 4.6+5.1

                         = 9.7 kgs

total mix required = 10kg

he need 10-9.7 = 0.3 kg

                         =300 grams mix he need more
