Question

3. Find the time when principal is Rs 12,000 Rate is 10%, so I is Rs 1500.​

Answer 1

Answer:

Step-by-step explanation:

let ' t ' be the time .

t=? , p= Rs. 12,000 , r=10% , c.i=1500

SI= Prt/100

BY THE PROBLEM ,

$1500=(12000*10*t)/100$

= 5/4

therefore time is 5/4 .

hope it helps

Answer 2

To find : time period  .

Given : principal = $12,000 \ Rs$  , Rate = $10 \ \%$  , S.I = $1500\ Rs$

Solution :

• We know that , the simple Interest of an amount is calculated by multiplying the interest rate by the principal amount and the time period. the time period in years.
• SI Formula :  $S.I = \frac{P\times R\times T}{100}$
• Putting the value in formula. we get

        $1500 =\frac{12000 \times 10\times T}{100} \\\\1500 = 120\times 10 \times T \\\\T = \frac{1500}{1200} \\\\ T =\frac{15}{12} \\\\ T = \frac{5}{4}$

Hence, the time period is $\frac{5}{4}$ years .  

Note : question for above solution is ( Find the time when principal is Rs 12,000 Rate is 10%, S.I is Rs 1500.​)
