Question

A taxidriver filled his car petrol tank 40 liter of petrol on monday the next day he filled the tank 50 liter of petrol if petrol cost is 44 per liter how much did he spend in all on petrol

Answer 1

Answer:

Petrol filled on Monday = 40 liter

Petrol filled on next day = 50 liter

Total petrol filled = 90 liter [40+50=90]

Now ,

Cost of 1 Liter petrol = Rs. 44

Therefore , Cost of 90 liter petrol = 44 × 90

= 44×(100-10)

=44×100-44×10

=4400 - 440

= 3960

Hence , he spents Rs.3960 on petrol.
