A girl decided to stock up on sweets for her birthday party, so she bought 105 sweets in January. The second month she bought twice that number of sweets. In March she bought thrice the number of sweets in February. If the sweets are to be shared equally among 45 guests, how many will each guest receive?
January: 105 sweets
February 105 x 2= 210
March: 210 x 3= 630
Therefore the total amount of sweet bought: 105+210+630 = 945

A boy bought 3 pens at $6 each, 5 pencils at $1 each and 2 folders at $45 each. He paid his bill with a $100 and a $20 note. What change did he receive?
Cost of 3 pens: $6 x 3= $18
Cost of 5 pencils: $1 x 5= 5
cost of 2 folders: $45 x 2= 90
Therefore the total cost = $(18 +5 +90)= $113
Change received: $120-$113)= $7
