Question

In what time 5600 amount to 6720 at 8% per annum?

Answer 1

Answer:

$\large\bold\red{2.5\:yrs.}$

Step-by-step explanation:

Given,

• Principal, p = ₹ 5600
• Amount, a = ₹ 6720

But,

We know that

• Simple intrest = Amount - Principal

Therefore,

We get,

• S.I = ₹ (6720 - 5600) = ₹ 1120

Also,

• Rate of interest p.a , r = 8%

Now,

Let the time taken is t yrs.

Therefore,

We get,

$= > 1120 = \frac{5600 \times8 \times t }{100} \\ \\ = > t = \frac{1120 \times 100}{5600 \times 8} \\ \\ = > t = \frac{112 \times 10}{56 \times 8} \\ \\ = > t = \frac{56 \times 20}{56 \times 8} \\ \\ = > t = \frac{20}{8} \\ \\ = > t = \frac{5}{2} \\ \\ = > t = 2.5$

Hence,

The required time is 2.5 yrs.
