Ex 2.2 Class 6 Maths Question 1.

Find the sum by suitable rearrangement:

(a) 837 + 208 + 363

(b) 1962 + 453 +1538 + 647

Solution:

Ex 2.2 Class 6 Maths Question 2.

Find the product by suitable rearrangement:

(a) 2 x 1768 x 50

(b) 4 x 166 x 25

(c) 8 x 291 x 125

(d) 625 x 279 x 16

(e) 285 x 5 x 60

(f) 125 x 40 x 8 x 25

Solution:

(a) 2 x 1768 x 50 = (2 x 50) x 1768

= 100 x 1768 = 176800

(b) 4 x 166 x 25 = (4 x 25) x 166

= 100 x 166 = 16600

(c) 8 x 291 x 125 = (8 x 125) x 291

= 1000 x 291 = 291000

(d) 625 x 279 x 16 = (625 x 16) x 279

= 10000 x 279 = 2790000

(e) 285 x 5 x 60 = 285 x (5 x 60)

= 285 x 300 = 85500

(f) 125 x 40 x 8 x 25 = (125 x 8) x (40 x 25)

= 1000 x 1000

= 1000000

Ex 2.2 Class 6 Maths Question 3.

Find the value of the following:

(a) 297 x 17 + 297 x 3

(b) 54279 x 92 + 8 x 54279

(c) 81265 x 169 – 81265 x 69

(d) 3845 x 5 x 782 + 769 x 25 x 218

Solution:

(a) 297 x 17 + 297 x 3 = 297 x (17 + 3)

= 297 x 20

= 5949

(b) 54279 x 92 + 8 x 54279

= 54279 x (92 + 8)

= 54279 x 100 = 5427900

(c) 81265 x 169 – 81265 x 69

= 81265 x (169 -69)

= 81265 x 100

= 8126500

(d) 3845 x 5 x 782 + 769 x 25 x 218

= 3845 x 5 x 782 + (769 x 5) x 5 x 218

= 3845x5x782 + 3845x5x218

= (3845 x 5) x (782+ 218)

=19225 x 1000

=19225000

Ex 2.2 Class 6 Maths Question 4.

Find the product using suitable properties :

(a) 738 x 103

(b) 854 x 102

(c) 258 x 1008

(d) 1005 x 168

Solution:

(a) 738 x 103 = 738 x (100 + 3)

= 738 x 100 + 738 x 3 = 73800 + 2214 = 76014

(b) 854 x 102 = 854 x (100 + 2)

= 854 x 100 + 854 x 2 = 85400 + 1708 = 87108

(c) 258 x 1008 = 258 x (1000 + 8)

= 258 x 1000 + 258 x 8 = 258000 + 2064 = 260064

(d) 1005 x 168 = (1000 + 5) x 168

= 1000 x 168 + 5 x 168

= 168000 + 840 = 168840
