Four friends jointly bought a plot worth Rs.5,60,000.For every 7 rupees Ajay paid, Bhanu paid 15 rupees and for every 5 rupees Bhanu paid, Chandu paid 12 rupees.The amount paid by Chandu and Deepak are in the ratio of 2:3.How much amount did Chandu spend on purchasing the plot?

To solve this problem, we need to follow these steps:

Step 1: Let's assume the amount paid by Ajay, Bhanu, Chandu, and Deepak as A, B, C, and D respectively.

Step 2: From the problem, we know that for every 7 rupees Ajay paid, Bhanu paid 15 rupees. So, we can write this as B = 15/7 A.

Step 3: Similarly, for every 5 rupees Bhanu paid, Chandu paid 12 rupees. So, we can write this as C = 12/5 B.

Step 4: We also know that the amount paid by Chandu and Deepak are in the ratio of 2:3. So, we can write this as C/D = 2/3 or D = 3/2 C.

Step 5: The total amount paid by all four friends is Rs.5,60,000. So, we can write this as A + B + C + D = 5,60,000.

Step 6: Now, we can substitute the values of B, C, and D from steps 2, 3, and 4 into the equation from step 5. This gives us A + 15/7 A + 12/5 * 15/7 A + 3/2 * 12/5 * 15/7 A = 5,60,000.

Step 7: Solving this equation will give us the value of A, which is the amount paid by Ajay.

Step 8: Once we have the value of A, we can substitute it back into the equations from steps 2, 3, and 4 to find the values of B, C, and D, which are the amounts paid by Bhanu, Chandu, and Deepak respectively.

Step 9: The value of C will be the amount paid by Chandu, which is what the problem is asking for.
