Dear student we can solve this problem in this way : –

The cost of petrol is 44 per litre.

Expenditure on 40 litres of petrol on Monday is = 44 X 40

And expenditure on 50 litres of petrol on Tuesday is = 50 X 44

Therefore, the total money he spent

= 44 × 40 + 50 × 44 = 44 (40 + 50) (Distributivity of multiplication over addition)

= 44 × 90

= 3960

∴ He spent Rs. 3960 in all on petrol.

Hope this solution helps you to dispel all your doubts about this question 🙂
