Question

Manish face baccha total of 20000 if principal letter borrowed was 15000 and the time period was five you what was the interest rate

​

Answer 1

Step-by-step explanation:

Let the first part lent at 6% be x and second part lent at 8% be (20000 - x)

Average interest received on total sum is 6.4%

Simple interest = (P × R × T)/100 = (20000 × 6.4 × 1)/100 = Rs. 1280

Total interest received = 1280

So, 1280 = (x × 6 × 1)/100 + [(20000 - x) × 8 × 1]/100

⇒ 128000 = 6x - 8x + 160000

First part, x = Rs. 16000

∴ Second part = 20000 - x = Rs. 4000
