Question 676483
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/Total Cost}}} = {{{500/1200}}} = ({{{500/1200}}}  {{{ 500/500}}}) = {{{1/24 }}}.

Montly installment is {{{1/24}}} of the total cost.

Q. 2

Convert all fractions to the same denominator.

 - Total weight of the cake = 3{{{3/4}}}kg = 3+({{{3/4}}}*{{{2/2}}})=3{{{6/8}}} kg

- Santosh has 1{{{1/8}}}kg

- Suma has 1 � = 1+({{{1/4}}}*{{{2/2}}})=1{{{2/8}}}kg

Total weight of cake minus Santosh�s piece minus Suma�s piece equals amount left: (3{{{6/8}}}) � (1 {{{1/8}}}) � (1{{{2/8}}}) = (1{{{3/8}}}) kg. Mohan was left with 1{{{3/8}}} kg of cake.

Q.3
Cost of book + Cost of pen = Total cost{{{13.25+12.15=25.40}}}
Total paid  � total cost = change received {{{50.00-25.40=24.60}}
Sheela received 24.50 back.	

Q.4
Convert all the amounts to the same unit. 1 kg = 1000 g.

Sugar = .75 kg x 1000 g = 750 g.
Flour = 1.5 kg x 1000 g = 1,500 g
Butter = 450 g
Eggs = 400 g. 
Total weigh = 750 + 1500 + 450 + 400 = 3100 g. 

Convert g. to kg: 3100g/1000g = 3.1 kg
The total weigh of the contents is 3.1 kg.

Q. 5
Distanced run + distanced cycled = total distance traveled. 
{{{0.575+3.50=4.075}}}
