Answer:

1- 81265 x 169 – 81265 x 69

= 81265 x (169 – 69)

= 81265 x 100

= 8126500

2-. 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

3- 728×101

=728×(100+1)

=728×100+728×1

=72800+728=73528

please mark as brainlest answer
