I think this is as per AS - 19 para 40
Lease income from operating leases should be recognized in the statement of profit and loss on a straight line basis over the lease term, unless another systematic basis is more representative of the time pattern in which benefit derived from the use of the leased asset is diminished.
If lease period is for 3 years and rent as per agreement is Rs. 20,000 per month for 1 st year, Rs. 25,000 per month for 2nd year and Rs. 30,000 per month for 3rd year then rent expenses should be booked Rs. 25,000 per month for all the three years.
