Question

at what rate of simple intrest p, a will a certain amount be thrice the principal amount after 6 years​

Answer 1

Answer:

33⅓ %

Step-by-step explanation:

Let the Rate be R and Principal be P.

Amount (A) = 3P

Simple Interest (SI) = A-P = 3P - P = 2P

Time (T) = 6 years

SI = PRT/100

=> 2P = P × R × 6/100

=> 2 = R × 3/50

=> 2 × 50/3 = R

=> R = 100/3 % = 33⅓ %
