Q IV) 

a) Divide and verifty your answer

63845 / 35

35 x 0 = 0

35 x 1 = 35

35 x 2 = 70

35 x 3 = 105

35 x 4 = 140

35 x 5 = 175

35 x 6 = 210

35 x 7 = 245

35 x 8 = 280

35 x 9 = 315

 

      1 8 2 4

------------------------

35 | 63845

-      35

-------------------

        288 

-       280

          0084 

-         0070

          00145 

-         00140

------------------

         00005  

Verify the answer: dividend = quotient x divisor + remainder

1824 x 34 + remainder ( 5) = 63840 + 5 = 63845

 

b) Which is the greatest 320 x 150 or 302 x 160. Find out by rounding off either of the factors to its nearest ten or hundred.

This problem is from Std VI mathematics class. Rounding of numbers is taught in class VI.

In product you round individual numbers. Secondly if the number is in hundred then round in hundred. Here all the 4 numbers are in hundred

so round all numbers in hundred. How do you round numbers see class VI mathematics notes on our website.

1) Round 320 which comes to 300

2) Round 150 which comes to 200

3) Round 302 which comes to 300

4) Round 160 which comes to 200

See the rounded numbers we come to the conclusion that product of both the numbers will be equal.

 

 

 

c) Rahim travelled 10.25 km on foot; 17.65 km by bus and the rest by cycle. If he covered a total distance of 35 km, find the distance he covered by cycle.

Total distance covered by rahim = 35 = rahim travelled by foot + travelled by bus + travelled by cycle

Therefore distance travelled by cycle = 35 - 10.25 - 17.65 =

Subtraction is done as shown below one number at a time. Subtraction is always done from greater number.

           35.00

-          10.25

----------------

            24.75

-           17.65

----------------------

               7.10 Km is the distance travelled on cycle.  

 

d) The following bar graph shows the number of students of Sheth C.N. English Medium School who subscribe to the magazine "Children World", fill in the blanks that follows:

 

bar

i) Give a title to the bar Chart Students subscribing to Children World Magazine

ii) The vertical scale of the graph shows No of Students in Classes

iii) Class III buys the maximum number of magazines. They buy 90 magazines

iv) Classes II and V buy the same number of magazines. Together they buy 60 + 60 = 120 magazines.

Even Class I and IV buy same number of magazines. Together they buy 30 + 30 = 60 magazines

 

e) There are 10 fisherwomen in the Meenkar Bank. Each of the women saves Rs. 150 per Month. Then find out:

i) How much will they save altogether in 1 month?

Answer: Use Cross Multiplication

1 women saves ===== Rs 150 per month

10 women saves ===== ?

? x 1 = 150 x 10 = 1500 Rs per month, ten women saves the money.

ii) How much money they will save in 1 year?

1 month they save =======1500 Rs

12 months ============?

? x 1 = 1500 x 12 = 18,000 Rs, ten women would save money in one year.

iii) How much will they save in 20 years?

1 year they save ====== Rs. 18,000

20 years they save ======? how much

? x 1 = 18000 x 20 = 3,60,000 Rs. will be the money saved by 10 women in 20 years.
