Question

Principal is ?, rate of interest is 5%, time is ?, Interest is 6000, amount is 18000.
Answer with solutions

Answer 1

Principal = 12000.

Time = 10

Step-by-step explanation:

Rate of Interest(R) = 5%

Interest(I) = 6000.

Amount = 18000

Interest(I)=PRT

Where P= Principal

R=Rate of Interest

T=Time

Amount = Interest+Principal

Substituting the known value

$\Rightarrow 18000=6000+P$

Isolate P by subtracting 6000 from both sides

$\Rightarrow 18000-6000=6000-6000+P\\\Rightarrow 12000=P\\\Rightarrow P=12000$

Now we know that

I=PRT

Substituting the known values

$\Rightarrow 6000=12000*.05\times T\\\\\Rightarrow 6000=600\times T\\\Rightarrow T=\frac{6000}{600} \\\\\Rightarrow T=10$

Answer 2

Answer : 12,000

Step-by-step explanation:

Total Interest = 6000 rupees

Total Amount = 18,000 rupees

Now, Principal (P) = Total Amount – Interest.

= 18,000 – 6000

= 12,000.

Hence, the principal is 12,000 rupees.
