Question

Find the time when: Principal = ₹ 5000, amount = ₹ 6450 and

rate = 12% p.a.​

Answer 1

Answer:

Interesr = amount - principal

6450- 5000=₹1450

time = interest × 100 / principal × rate

= 1450× 100 / 5000 × 12= 2.5 yrs

Answer 2

Answer:

$interest = amount - principal$

$interest = 6450 - 5000$

$interest = 1450$

$interest = \frac{p \times r \times t}{100}$

$1450 = \frac{5000 \times 12 \times t}{100}$

$1450 \times 100 = 5000 \times 12 \times t$

$145000 = 60000 \times t$

$t = \frac{145000}{60000}$

$t = 2.41$
