Question

in what time will ₹45000 amounts to ₹63000, if the simple interest is calculated 10% per annum?​

Answer 1

SOLUTION

• Principal = ₹ 45000
• Amount = ₹ 63000
• Rate = 10% p.a.

• Simple interest = A -P
• Simple interest = 63000 - 45000
• Simple interest = 18000
• (P×R×T)/100 = 18000
• 45000 × 10 × T = 18000×100
• T = (18000×100)/(45000×10)
• T = 4 year.

Mark as b. list.

Thankyou.

Answer 2

Answer:

T = 4 years.

Step-by-step explanation:

Principal = ₹45,000

Amount = ₹63,000

Rate = 10% p.a.

Simple interest = A -P

In general, the simple interest paid or received for a period is a fixed percentage of the principal amount that was borrowed or lent.

Compound interest accrues and is added to accumulated interest from previous periods, so borrowers must pay interest on both interest and principal.

Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan. Interest, usually expressed as a percentage, can be simple or compound. Simple interest is based on the principal of the loan or deposit. In contrast, compound interest is based on the amount of principal and interest that accrues on it each period. Simple interest is calculated only on the principal of the loan or deposit, so it is easier to determine than compound interest.

Simple interest = 63000 - 45000

Simple interest = 18000

(W*W*D)/100 = 18000

45,000*10*T = 18,000*100

T = (18000*100)/(45000*10)

T = 4 years.

OR

We have to find time to make Rs 45,000 to Rs 63,000 at 10% p.a.

S.I = A - P

S.I = 63,000 - 45,000

S.I = 18,000

Formula to find the time:-

T = S.I*100/P*R

T = 18,000*100/45,000*10

T = 4 years.
