Answers

Answered by rahul72799

Answer:

Step-by-step explanation:

Given

Amount = Rs 3400

Rate = 1%

Time = 3 yr

Let the principle be ₹ P.

SI = (PTR/100) = (P x 3 x 12)/100 = ₹ 36P/100

A = (P + SI) = P + 36P/100 = ₹ 136P/100

⇒ 136P/100 = 3400

⇒ P = (3400 x 100)/136 = 2500

∴ Sum = ₹ 2500

hope it is helpful

astudent72: 3400 is amount not principle

astudent72: we have to find the principal

astudent72: A = ₹ 3400 T = 3 yr , R = 1% per month = 12 % per annum Let the principle be ₹ P.
SI = (PTR/100) = (P x 3 x 12)/100 = ₹ 36P/100
A = (P + SI) = P + 36P/100 = ₹ 136P/100
⇒ 136P/100 = 3400
⇒ P = (3400 x 100)/136 = 2500
∴ Sum = ₹ 2500

astudent72: this is the right answer

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?
