Fabina borrows ₹12,500at12%per annum for 3 year at simple interest and Radha borrows the same amount for tje same time period at 10%per annum,compounded annually.who pays more interest and by how much?

Posted by Vinod Rawat 7 years, 4 months ago

CBSE > Class 08 > Mathematics

1 answers

Sonali Aggarwal 7 years, 4 months ago

Fabina borrows 12500 at simple interest

I = PRT/100

= 12500*12*3/100

= 4500Rs

Radha borrows 12500 at compound interest

A = P{1+r/100}n

⁼12500[1+0.1}3

= 12500*1.331

=16637.5

I =16637.5-12500

= 4137.5

Fabina pays more interest by 4500-4137.5= Rs 362.5

Posted by Virendra Kumar 7 years, 4 months ago

Yogita Ingle 7 years, 4 months ago

Let the original salary of officer be 100.
Therefore increased salary = (125/100) (100) = 125
Amount to be decreased from increased salary to obtain original salary = 125 - 100 = 25
Percentage to be reduced = (25/125) × 100 = (1/5) × 100 = 20%
