Question

divide 30000 into two part thatched simple interest on the first part for 2 years at 8 percent per annum is equal to the simple interest on the second part for 4 years at the same rate of interest ​

Answer 1

Answer:

The part are 1080 rupees and 2920 rupees.

Step-by-step explanation:

Here, the total money = 3000 rupees.

Let x be the first part

• Second part = 3000 - x

According to the question

The simple interest on the first part for 4 year at 8% per annum = The simple interest on the second part for 2 year at 9% per annum

= x × 4 ×8 = ( 3000 - x ) × 4 ×8

100 100

= 32x = 18 ( 3000 - x )

100 100

= 3200x = 1800 ( 3000 - x )

3200x = 5400000 - 1800x ➡️ 5000x = 5400000 ➡️ x = 1080

Thus , the first part = x = 1080 rupees

Second part = 3000 - x = 3000 - 1080 =

2920 Rupees
