Answer 1

Answer:

• Petrol filled on Monday = 40 liters

Petrol filled on next day = 50liters

Total petrol filled = 90liters

Now, Cost of 1 liter petrol = Rs. 44

Cost of 90 liters petrol = 44 x90

= 44 x (100 – 10)

= 44 x 100 – 44 x10

= 4400 – 440

= Rs. 3960

Therefore, he spent Rs. 3960 on petrol.

• Quantity of milk supplied in da morning=32 liters

quantity of milk supplied in da evening = 68 litres

⇒ total milk per litre = (32+68) litre

⇒cost of milk per litre = rs 15

∴ total cosr per day = 15*(32+68) 

                               =15*100

                                = rs 1500
