5. A weaver who had taken a loan of 40,000 from amoneylender finds that he has to pay 44,500 to clearhis dues after only 75 days. Find the annual rate ofsimple interest charged by the moneylender. About the author Aubrey
Answer: Simple Interest = Amount – Principal = 44,500 – 40,000 = 4,500 . T = 75 Days = 2½ months . r = \frac{si \times 100}{p \times t}r= p×t si×100 . r = \frac{4500 \times 100}{40000 \times \frac{5}{2} }r= 40000× 2 5 4500×100 In tha above step you can directly divide 40000 by 2 to get r = \frac{4500 \times 100}{20000 \times 5}r= 20000×5 4500×100 r = \frac{9}{2}r= 2 9 r = 4.5\%r=4.5% Reply
Answer:
Simple Interest = Amount – Principal
= 44,500 – 40,000
= 4,500
.
T = 75 Days
= 2½ months
.
r = \frac{si \times 100}{p \times t}r=
p×t
si×100
.
r = \frac{4500 \times 100}{40000 \times \frac{5}{2} }r=
40000×

5
4500×100
In tha above step you can directly divide 40000 by 2 to get
r = \frac{4500 \times 100}{20000 \times 5}r=
20000×5
4500×100
r = \frac{9}{2}r=

r = 4.5\%r=4.5%
