Question

If 2/3 part of a land costs Rs 45000, find the cost of 4/5 part of the land.

a) Rs 54,000
b) Rs 50,000
c) Rs 60,000
d) Rs 48,000

Answer 1

The cost of the entire land was determined by finding the value of the whole based on the 2/3 part given. Then, the cost for 4/5 of the land was calculated from the total cost, yielding Rs 54,000.

Step-by-step explanation:

First, we calculate the cost of the entire land based on the cost of the 2/3 portion given. If 2/3 of the land costs Rs 45,000, then the full land (which is 3/3 or 1 whole), would cost:

(3/2) × Rs 45,000 = Rs 67,500

Next, we find out what 4/5 part of the land would cost, using the total value determined:

(4/5) × Rs 67,500 = Rs 54,000

The cost of 4/5 part of the land is Rs 54,000, which corresponds to option (a).
