Question

AN AMOUNT OF MONEY INVESTED TREBLED IN 6 YEARS .FIND THE RATE OF INTEREST EARNED.

Answer 1

Answer:

Rate of Interest = 33.33%

Step-by-step explanation:

Let Principal = x

Amount = 3x

Simple Interest = Amount - Principal

                          = 3x - x

                          = 2x

Simple Interest = Principal × Rate × Time

2x = x × Rate × 6

⇒ 6x × Rate = 2x

⇒ Rate = 0.3333

⇒ Rate = 0.3333 × 100

⇒ Rate = 33.33%

Answer 2

Answer:33 1/3

Step-by-step explanation: As the money is invested we can take it as principal. But, the principal is not given so we will assume it as ₹100.

Amount=100*3 [An amount of money invested 'trebled '----]

Time=6 years[An amount of money invested trebled in '6 years']

Amount=P-Simple interest

Amount-P=simple interest

300-100=200

S.I.=P*R*T/100

200=100*R*6/100

200=R*6

200/6=R

100/3=R

'33 1/3'=R
