He saves Rs. 30(x - y) in 30 days
Step-by-step explanation:
Given that, Lalit earns Rs. x per day.
∴ in 30 days, he earns Rs. 30x in total
Also he spends Rs. y per day.
∴ in 30 days, he spends Rs. 30y in total
∴ total savings of his in 30 days
= money earned in 30 days - money spent in 30 days
= Rs. (30x - 30y)
= Rs. 30 (x - y)
