Q.1
Total Cost: 12,000
� paid in cash: 12,000/4 = 3000
Paid with check: 4000
- Total cost (12,000) minus amount paid in cash (3000) minus amount paid with check (4000) = Amount left to pay (5000)
- Amount left to pay (5000) divided by number of installments (10) = monthly installment (500).
- Monthly+Installment%2FTotal+Cost = 500%2F1200 = (500%2F1200 +500%2F500) = 1%2F24+.
Montly installment is 1%2F24 of the total cost.
Q. 2
Convert all fractions to the same denominator.
- Total weight of the cake = 33%2F4kg = 3+(3%2F4*2%2F2)=36%2F8 kg
- Santosh has 11%2F8kg
- Suma has 1 � = 1+(1%2F4*2%2F2)=12%2F8kg
Total weight of cake minus Santosh�s piece minus Suma�s piece equals amount left: (36%2F8) � (1 1%2F8) � (12%2F8) = (13%2F8) kg. Mohan was left with 13%2F8 kg of cake.
Q.3
Cost of book + Cost of pen = Total cost13.25%2B12.15=25.40
Total paid � total cost = change received
