Question

in 4 years Rupees 6000 amount to rupees 8,000 in what time will rupees 525 amount to rupees 700 at the same rate

Answer 1

As the money becomes 8000 from 6000 in 4 years
So S.I=8000-6000
Or S.I=2000
Now formulae of S.I=P*R*T/100
Or 2000=6000*R*4/100
Or 2000=60*R*4
Or 2000=240R
Or R=2000/240
Or R=50/6
Or R=25/3
Or R=8.33%
Now at what time 525 become 700
S.I=700-525
OR S.I=175
S.I.=P*R*T/100
OR 175=525*25*T/100*3(TAKING R=25/3)
OR 175=525*1*T/4*3
OR 175*12=525T
OR T=175*12/525
OR T=7*12/21
OR T=12/3
OR T=4 YEARS
