Question

find time a. Principal - 600 S. Intrest = 12.60 3.51 - Rate = 3.5%​

Answer 1

Answer:

Appropriate Question :-

• Find time when the principal is Rs 600, simple interest is Rs 12.60 and the rate is 3.5%.

Given :-

• A sum of Rs 600, simple interest is Rs 12.60 and the rate of interest is 3.5%.

To Find :-

• What is the time.

Formula Used :-

$\clubsuit$ Time Period Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{T =\: \dfrac{S.I \times 100}{P \times r}}}}\: \: \: \bigstar$

where,

• T = Time Period
• S.I = Simple Interest
• P = Principal
• r = Rate of Interest

Solution :-

Given :

• Principal = Rs 600
• Simple Interest = Rs 12.60
• Rate of Interest = 3.5% per annum

According to the question by using the formula we get,

$\implies \bf T =\: \dfrac{S.I \times 100}{P \times r}$

$\implies \sf T =\: \dfrac{12.60 \times 100}{600 \times 3.5}$

$\implies \sf T =\: \dfrac{126\cancel{0}}{210\cancel{0}}$

$\implies \sf T =\: \dfrac{\cancel{126}}{\cancel{210}}$

$\implies \sf T =\: \dfrac{3}{5}$

$\implies \sf\bold{\red{T =\: 0.6\: years}}$

$\therefore$ The time period is 0.6 years .

Answer 2

Answer:

P=600

Si=12.60

R=3.5

T=?

: Si=P×R×T

100

: T=SI×100

P×R

= 12.60×100

: 600×3.5

= 1260

: 2100

126

: = 210

= 5
