Solutions:
1) Petrol filled on Monday = 40 liters
Petrol filled on next day = 50 liters
Total petrol filled = 90 liters
Now, Cost of 1 liter petrol = Rs. 44
Cost of 90 liters petrol = 44 x 90
= 44 x (100 – 10)
= 44 x 100 – 44 x10
= 4400 – 440
= Rs. 3960
Therefore, he spent Rs. 3960 on petrol.

2) Amount of milk supplied in the morning = 32
Amount of milk supplied is the evening = 681
Total of milk per litre = (32+ 68)
Cost of milk per litre = Rs 15
Total cost per day = 15 × (32 + 68)
= 15 × 100
= Rs 1500
Hence, If the milk costs Rs. 15per litre, then Rs 1500 is due to the vendor per day.

3) (a) 1+0 =1
It does not represent zero
(b) 0 x 0 = 0
It represents zero
(c) 0/2 = 0
It Represents zero
(d) 10-10/ 2 = 0
It represents zero
------------------------------------------------------------------
4) Yes, if the product of two whole numbers is zero, then one or both of them will definitely be zero. In mathematics, whole numbers are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on.
All-natural numbers are whole-numbers.
All whole-numbers are not natural numbers.
Examples:
(i) 8 x 0 = 0 and 0 x 14 = 0
One number is zero here.
(ii) 0 x 0 = 0
Both the numbers are zero here

5) Given
If the product of two whole number is 1, can we say that one or both of them will be 1?
Find out
We need to justify the given statement
Justification
If the two numbers’ product is one, then both numbers need to be equal to 1 only.
If only one number were 1, then the product cannot be
Examples:
1 x 1 =1
Both the numbers are 1, and hence the product is 1
5 x 1 = 5
4 x 1 = 4
8 x 1 =8
One of the numbers is not equal to 1, and hence the product is not 1
Answer:
Hence, If the product of two whole number is 1, then both the whole numbers should be 1.

6) (a) 728× 101
=729× (100+1)
=728× 100 + 728× 1
=72800 + 728
=73528
(b) 5437 × 1001
=5437 × (1000+1)
= 5437× 1000 + 5437× 1
=5437000 + 5437
=5442437
(c) 824× 25
= 824 × (20+5)
= 824× 20 + 824 × 5
=16480+4120
=20600
(d) 4275× 125
=4275× (100+20+5)
=4275× 100 + 4275× 20 +4275× 5
=427500 + 85500 + 21375
= 534375
(e) 504 × 35
= 35× (500+4)
= 35× 500 + 35× 4
=17500 + 140
=17640
