Question

how many years will it take to double amount of rupee 1000 if the simple interest is 10%?​

Answer 1

Answer:

The answer will be 10 years

Answer 2

Answer:

we know that,

SI=PRT/100 where SI=SIMPLE INTEREST,

P=PRICIPAL VALUE, R=RATE OF INTEREST PER ANNUM, T=TIME TILL WHICH INTEREST TO BE SOLVED

since in the question it is given that,

P=1000

R=10%

Step-by-step explanation:

STEP-1 (CALCULATING SI)

we have to double the pricipal ammount that is

2000

so total ammount is 2000

P=1000

we know that AMOUNT = SI + P

THEREFOR,

SI = AMMOUNT - P

SI=2000-1000

SI=1000

STEP-2 (CALCULATING TIME PERIOD)

from earlier discussion we know that

SI=PRT/100

putting all the values

P=1000

R=10%

SI=1000

NOW

1000= 1000*10*T/100

on calculating we will get

T=10 years
