Answer:
Cheapest cost to pay = £906
Step-by-step explanation:
Given that:
Rice to supply = 50 tonnes
Option A:
Big van has capacity of 15 tonnes.
Number of big vans =
It means that 4 big vans will be needed for transporting 50 tonnes of rice.
Cost of 4 vans = 4*250 = £1000
Option B:
Small van has capacity of 9 tonnes.
Number of small vans =
It means that 6 small vans will be nedded for transporting 50 tonnes of rice.
Cost of 6 vans = 6*151 = £906
Therefore,
The company can transport the rice through small vans.
Hence,
Cheapest cost to pay = £906
Given,
Perimeter of rectangle = 64 units.
Width = y = 11 units
Let,
Length = 20 units, as discussed in the question
Perimeter of rectangle = 2( length + width )
Solving Left Hand Side,
= > Perimeter of rectangle
= > 64 units [ Given ]
Solving Right Hand Side ,
= > 2( 20 + 11 )
= > 2( 31 )
= > 2 × 31
As we can see that 64 ≠ 62
64 ≠ 2( x + y )
Divide by 2 on both sides,
32 ≠ x + y
Hence, option B is correct.
Perimeter of rectangle = 64 units.
Width = y = 11 units
Let,
Length = 20 units, as discussed in the question

Solving Left Hand Side,

= > 64 units [ Given ]
Solving Right Hand Side ,
