Answer :

Answer:

rent paid in one year = Rs. 1,44,000

rent for every 3 months = Rs. 42,000

monthly profit = Rs. 2000

Step-by-step explanation:

i.

let x be the rent paid in one year

as per given:

for 3 months rent paid = Rs. 36000

for 12 months rent paid = x

x/36000 = 12/3

x = 4 * 36000 = Rs. 1,44,000

thus,

rent paid in one year = Rs. 1,44,000

ii.

let x be the rent paid in one month

as per given:

in 3 months rent paid = Rs. 36000

in 1 month rent paid = x

x/36000 = 1/3

x = 36000/3 = Rs. 12000

per month increment = Rs. 2000

after increment per month rent = 12000 + 2000 = Rs. 14000

rent for every 3 months = 3 * 14000 = Rs. 42,000

iii.

monthly profit = new monthly rent - old monthly rent

                        = 14000 - 12000 = Rs. 2000
