Question

in how many years will rupees 870 amount to 1044 the rate of the interest being 2 whole 1 by 2% per annum,,,,
please answer this question please

Answer 1

HEY THERE!!!

$\huge{\bold{SOLUTION :-}}$

Method Of Solution:-

➡ Given:

→ ‎Amount( A )= Rs 1044

→ Rate ( R) = 5/2% 

→ Principal (P) = 870

→Amount (A) = 1044

→ SI = Amount - Principal

➡ SI = 1044 - 870

➡ SI = 174

➡ To Find:

→ Time(P) = ? 

→ Now,Using Formula

We know SI = P× R × T/1000

➡ Substitute the Given value in Simple Interest Formula!!

➡ SI = P × R × T /100

➡ 174 = 870 × 5/2 × T /100

➡ 174 = 435 × 5 × T /100

➡ 17400 = 2175 × T

➡ T = 17400/2175

➡ T = 8 Years

Hence, ➡ Required Time be 8 Years.

Answer 2

$\huge \bold {Solution :-}$

$\rule {135} {2}$ $<b>$

Some of abbreviations used :-

A :- Amount
P :- Principal
R :- Rate
T :- Time
S. I :- Simple Interest

$\rule {168} {2}$

Given :-

Amount :- ₹1044

Rate :- 5/2 % p.a

Principal :- ₹ 870

$\rule {168} {2}$

We know that,

S. I = A - P

S. I = 1044 - 870

Therefore,

S. I = 174


Now, we have to find Time by using

S.i = p × r × t/ 100

174 = 870 × 5/2 × t/100

174 = 435 × 5/ 100

T = 174 × 100 / 2175

T = 17400/ 2175

T = 8

Therefore,

Time is 8 years

$\rule {168} {2}$
