1.	at what rate of simple intrest p, a will a certain amount be thrice the principal amount after 6 years
Answer» ong>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 %

Answer»

ong>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 %
