Question

. In how many years Rs. 700 will amount to Rs. 847 at compound interest of p.c.p.a. ?​

Answer 1

Answer:

In 2 years

Step-by-step explanation:

Principal = Rs.700

Amount = Rs.847

Rate of Interest = 10%

A = P(1+R/100)^n  ( n = number of years )

847 = 700(1+10/100)^n

847/700 = (11/10)^n

121/100 = (11/10)^n

(11/10)^2 = (11/10)^n

Since the bases are same , equating the powers -

n = 2 years

Answer 2

$\bold{ANSWER≈}$

In 2 years

Step-by-step explanation:

Principal = Rs.700

Amount = Rs.847

Rate of Interest = 10%

A = P(1+R/100)^n (n = number of years)

847=700(1+10/100)^n

847/700 (11/10)^n

=

121/100 = (11/10)^n

(11/10)^2 = (11/10)^n

Since the bases are same, equating the powers -

n = 2 years
