Answer 1

Answer:

Step-by-step explanation:

Principal (P) = Rs 1800

Rate of interest (r) = 10% p.a

Let Time = T years

Number of times interest paid = n

Compound interest (C.I) = Rs378

Amount (A) = P+C.I

= Rs 1800 + Rs 378

= Rs 2178

We know that,

Now , substitute the values in the above formula, we get

/* we know the Exponential Law:

*/

Therefore,

Number of times interest paid (n) = 2

Time (T) = 2 years
