Question

Q. A part of Rs 77,600 is lent out at 6% per six months. The rest of the amount is lent out at 5% per annum after one year. The ratio of interest after 3 years from the time when first amount was lent out is 5 : 4. Find the second part that was lent out at 5%.

• A. Rs 20,000
• B. Rs 40,000
• C. Rs 57,600
• D. Rs 66,600

Answer 1

The correct option is C Rs 57,600

Let the money lent out be x and 77600-x
Then
$x\times \frac{12}{100}\times :\frac{(77600-x{)}^5}{100}\times 2=5:44\times .36x=5\times \frac{77600-x}{10}2.88x+x=77600x=\frac{77600}{3.88}=20000$
Amount lent out at 5% = 77600- 20000 = 57600
