Question

In 4 years, Rupees 6,000 amounts to Rupees 8,000. In what time will Rupees 525 amount to Rupees 700 at same rate. ​

Answer 1

Answer:

4 years

Step-by-step explanation:

It is given that P=Rs.6,000

A=Rs.8,000

We know that S.I=A−P

Substituting the values =8000−6000=Rs.2000

Also, duration is given as T=4 years

Here,

Rate (R) = (S.I×100)/(P×T)

Substituting the values =(2000×100)/(6000×4)

=25/3%=8(1/3)% p.a

Now, we need to find the time that will result to an amount of Rs.700 at same rate.

So,

P=Rs.525

A=Rs.700

S.I=A−P

       =700−525=Rs.175

Also, Rate (R)=25/3% p.a

So,

Time (T)= (S.I×100)/(P×R)

Substituting the values  =(175×100×3)/(525×25)

                                       =4

So we get  =4 years
