Question

Find T= ?, if P= ₹600, A=₹850, R=3%.
I need step by step explanation. please ans fast​

Answer 1

Let the time be x

formula of simple intrest =

$t \times p \times r \div 100$

so ,

$x \times 600 \times 3 \times \div 100 = 250 \\ x \times 2 = 250 \\ \\ x = 250 \div 2 \\ x = 125$

what is the meaning of A=850

❍ Here, the question has given us the principal, amount and rate of interest. Now, the question has asked us to find out the time. So, to find the time first of all we will find the simple interest by subtracting the principal from the amount then we will simply apply the formula of time and can easily get the time.

ANSWER:-

⇒ Time is 13.8 years.

GIVEN:-

⇒ Principal = ₹ 600

⇒ Amount = ₹ 850

⇒ Rate = 3%

TO FIND:-

⇒ Time = ?

FORMULA:-

⇒ Time = (100 × Interest)/(P × R)

SOLVING BY APPLYING THE FORMULA:-

⇒ Principal = ₹ 600

⇒ Amount = ₹ 850

⇒ Rate = 3%

⇒ Time = (100 × Interest)/(P × R)

• Finding the simple interest:-

➭ Simple Interest = Amount - Principal

➭ Simple Interest = ₹ 850 - ₹ 600

➭ Simple Interest = ₹ 850 - ₹ 600 = ₹ 250

➭ Simple Interest = ₹ 250

The interest is of Rs. 250.

• Finding the time:-

➭ Time = 100 × 250 / 600 × 3

➭ Time = 25,000 / 1,800

➭ Time = 25,000 / 1,800 = 13.8

➭ Time = 13.8 years

Time is 13.8 years.

${\underline{\boxed{\large{\mathscr{\:More\:Formulae\: :—}}}}}$

• S. I = (P × R× T)/100
• Rate = (100 × S.I)/(P × T)
• Amount = P + S.I
• Time = (100 × Interest)/(P × R)
• Principal = 100×Amount/100+(R×T)
